Abstract
This document has been developed and approved by the Printer
Working Group (PWG) as a PWG standard. It is intended to be
distributed as an Informational RFC. This document provides a
printer industry standard SNMP MIB for (1) monitoring the status
and progress of print jobs (2) obtaining resource requirements
before a job is processed, (3) monitoring resource consumption
while a job is being processed and (4) collecting resource
accounting data after the completion of a job. This MIB is
intended to be implemented (1) in a printer or (2) in a server

that supports one or more printers. Use of the object set is not
limited to printing. However, support for services other than
printing is outside the scope of this Job Monitoring MIB. Future
extensions to this MIB may include, but are not limited to, fax
machines and scanners.

Job Monitoring MIB
1 Introduction
This specification defines an official Printer Working Group (PWG)
[PWG] standard SNMP MIB for the monitoring of jobs on network printers.
This specification is being published as an IETF Information Document
for the convenience of the Internet community. In consultation with
the IETF Application Area Directors, it was concluded that this MIB
specification properly belongs as an Information document, because this
MIB monitors a service node on the network, rather than a network node
proper.
The Job Monitoring MIB is intended to be implemented by an agent within
a printer or the first server closest to the printer, where the printer
is either directly connected to the server only or the printer does not
contain the job monitoring MIB agent. It is recommended that
implementations place the SNMP agent as close as possible to the
processing of the print job. This MIB applies to printers with and
without spooling capabilities. This MIB is designed to be compatible
with most current commonly-used job submission protocols. In most
environments that support high function job submission/job control
protocols, like ISO DPA[iso-dpa], those protocols would be used to
monitor and manage print jobs rather than using the Job Monitoring MIB.
The Job Monitoring MIB consists of a General Group, a Job Submission ID
Group, a Job Group, and an Attribute Group. Each group is a table.
All accessible objects are read-only. The General Group contains
general information that applies to all jobs in a job set. The Job
Submission ID table maps the job submission ID that the client uses to
identify a job to the jmJobIndex that the Job Monitoring Agent uses to
identify jobs in the Job and Attribute tables. The Job table contains
the MANDATORY integer job state and status objects. The Attribute
table consists of multiple entries per job that specify (1) job and
document identification and parameters, (2) requested resources, and
(3) consumed resources during and after job processing/printing. A
larger number of job attributes are defined as textual conventions that
an agent SHALL return if the server or device implements the
functionality so represented and the agent has access to the
information.
1.1 Types of Information in the MIB
The job MIB is intended to provide the following information for the
indicated Role Models in the Printer MIB[print-mib] (Appendix D - Roles
of Users).
Bergman, Hastings, Isaacson, Lewis Informational [Page 6]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
User:
Provide the ability to identify the least busy printer. The user
will be able to determine the number and size of jobs waiting for
each printer. No attempt is made to actually predict the length
of time that jobs will take.
Provide the ability to identify the current status of the user's
job (user queries).
Provide a timely indication that the job has completed and where
it can be found.
Provide error and diagnostic information for jobs that did not
successfully complete.
Operator:
Provide a presentation of the state of all the jobs in the print
system.
Provide the ability to identify the user that submitted the print
job.
Provide the ability to identify the resources required by each
job.
Provide the ability to define which physical printers are
candidates for the print job.
Provide some idea of how long each job will take. However, exact
estimates of time to process a job is not being attempted.
Instead, objects are included that allow the operator to be able
to make gross estimates.
Capacity Planner:
Provide the ability to determine printer utilization as a
function of time.
Provide the ability to determine how long jobs wait before
starting to print.
Accountant:
Provide information to allow the creation of a record of
resources consumed and printer usage data for charging users or
groups for resources consumed.
Provide information to allow the prediction of consumable usage
and resource need.
Bergman, Hastings, Isaacson, Lewis Informational [Page 7]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
The MIB supports printers that can contain more than one job at a time,
but still be usable for low end printers that only contain a single job
at a time. In particular, the MIB supports the needs of Windows and
other PC environments for managing low-end direct-connect (serial or
parallel) and networked devices without unnecessary overhead or
complexity, while also providing for higher end systems and devices.
1.2 Types of Job Monitoring Applications
The Job Monitoring MIB is designed for the following types of
monitoring applications:
1. Monitor a single job starting when the job is submitted and
ending a defined period after the job completes. The Job
Submission ID table provides the map to find the specific job
to be monitored.
2. Monitor all 'active' jobs in a queue, which this specification
generalizes to a "job set". End users may use such a program
when selecting a least busy printer, so the MIB is designed for
such a program to start up quickly and find the information
needed quickly without having to read all (completed) jobs in
order to find the active jobs. System operators may also use
such a program, in which case it would be running for a long
period of time and may also be interested in the jobs that have
completed. Finally such a program may be used to provide an
enhanced console and logging capability.
3. Collect resource usage for accounting or system utilization
purposes that copy the completed job statistics to an
accounting system. It is recognized that depending on
accounting programs to copy MIB data during the job-retention
period is somewhat unreliable, since the accounting program may
not be running (or may have crashed). Such a program is also
expected to keep a shadow copy of the entire Job Attribute
table including completed, canceled, and aborted jobs which the
program updates on each polling cycle. Such a program polls at
the rate of the persistence of the Attribute table. The design
is not optimized to help such an application determine which
jobs are completed, canceled, or aborted. Instead, the
application SHOULD query each job that the application's shadow
copy shows was not complete, canceled, or aborted at the
previous poll cycle to see if it is now complete or canceled,
plus any new jobs that have been submitted.
The MIB provides a set of objects that represent a compatible subset of
job and document attributes of the ISO DPA standard[iso-dpa] and the
Internet Printing Protocol (IPP)[ipp-model], so that coherence is
maintained between these two protocols and the information presented to
end users and system operators by monitoring applications. However,
the job monitoring MIB is intended to be used with printers that
implement other job submitting and management protocols, such as IEEE
1284.1 (TIPSI)[tipsi], as well as with ones that do implement ISO DPA.
Bergman, Hastings, Isaacson, Lewis Informational [Page 8]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
Thus the job monitoring MIB does not require implementation of either
the ISO DPA or IPP protocols.
The MIB is designed so that an additional MIB(s) can be specified in
the future for monitoring multi-function (scan, FAX, copy) jobs as an
augmentation to this MIB.
2 Terminology and Job Model
This section defines the terms that are used in this specification and
the general model for jobs in alphabetical order.
NOTE - Existing systems use conflicting terms, so these terms are
drawn from the ISO 10175 Document Printing Application (DPA)
standard[iso-dpa]. For example, PostScript systems use the term
session for what is called a job in this specification and the term
job to mean what is called a document in this specification.
Accounting Application: The SNMP management application that copies
job information to some more permanent medium so that another
application can perform accounting on the data for Accountants, Asset
Managers, and Capacity Planners use.
Agent: The network entity that accepts SNMP requests from a monitor or
accounting application and provides access to the instrumentation for
managing jobs modeled by the management objects defined in the Job
Monitoring MIB module for a server or a device.
Attribute: A name, value-pair that specifies a job or document
instruction, a status, or a condition of a job or a document that has
been submitted to a server or device. A particular attribute NEED NOT
be present in each job instance. In other words, attributes are
present in a job instance only when there is a need to express the
value, either because (1) the client supplied a value in the job
submission protocol, (2) the document data contained an embedded
attribute, or (3) the server or device supplied a default value. An
agent MAY represent an attribute as an entry (row) in the Attribute
table in this MIB in which entries are present only when necessary.
Attributes are identified in this MIB by an enum.
Client: The network entity that end users use to submit jobs to
spoolers, servers, or printers and other devices, depending on the
configuration, using any job submission protocol over a serial or
parallel port to a directly-connected device or over the network to a
networked-connected device.
Device: A hardware entity that (1) interfaces to humans, such as a
device that produces marks on paper or scans marks on paper to produce
an electronic representation, (2) accesses digital media, such as CD-
ROMs, or (3) interfaces electronically to another device, such as sends
FAX data to another FAX device.
Bergman, Hastings, Isaacson, Lewis Informational [Page 9]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
Document: A sub-section within a job that contains print data and
document instructions that apply to just the document.
Document Instruction: An instruction specifying how to process the
document. Document instructions MAY be passed in the job submission
protocol separate from the actual document data, or MAY be embedded in
the document data or a combination, depending on the job submission
protocol and implementation.
End User: A user that uses a client to submit a print job. See
"user".
Impression: For a print job, an impression is the passage of the
entire side of a sheet by the marker, whether or not any marks are made
and independent of the number of passes that the side makes past the
marker. Thus a four pass color process counts as a single impression,
as does highlight color. Impression counters count all kinds:
monochrome, highlight color, and full process color, while full color
counters only count full color impressions, and high light color
counters only count high light color impressions.
One-sided processing involves one impression per sheet. Two-sided
processing involves two impressions per sheet. If a two-sided document
has an odd number of pages, the last sheet still counts as two
impressions, if that sheet makes two passes through the marker or the
marker marks on both sides of a sheet in a single pass. Two-up
printing is the placement of two logical pages on one side of a sheet
and so is still a single impression. See "page" and "sheet".
NOTE - Since impressions include blank sides, it is suggested that
accounting application implementers consider charging for sheets,
rather than impressions, possibly using the value of the sides
attribute to select different charges for one-sided versus two-sided
printing, since some users may think that impressions don't include
blank sides.
Internal Collation: The production of the sheets for each document copy
performed within the printing device by making multiple passes over
either the source or an intermediate representation of the document.
Job: A unit of work whose results are expected together without
interjection of unrelated results. A job contains one or more
documents.
Job Accounting: The activity of a management application of accessing
the MIB and recording what happens to the job during and after the
processing of the job.
Bergman, Hastings, Isaacson, Lewis Informational [Page 10]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
Job Instruction: An instruction specifying how, when, or where the job
is to be processed. Job instructions MAY be passed in the job
submission protocol or MAY be embedded in the document data or a
combination depending on the job submission protocol and
implementation.
Job Monitoring (using SNMP): The activity of a management application
of accessing the MIB and (1) identifying jobs in the job tables being
processed by the server, printer or other devices, and (2) displaying
information to the user about the processing of the job.
Job Monitoring Application: The SNMP management application that End
Users, and System Operators use to monitor jobs using SNMP. A monitor
MAY be either a separate application or MAY be part of the client that
also submits jobs. See "monitor".
Job Set: A group of jobs that are queued and scheduled together
according to a specified scheduling algorithm for a specified device or
set of devices. For implementations that embed the SNMP agent in the
device, the MIB job set normally represents all the jobs known to the
device, so that the implementation only implements a single job set.
If the SNMP agent is implemented in a server that controls one or more
devices, each MIB job set represents a job queue for (1) a specific
device or (2) set of devices, if the server uses a single queue to load
balance between several devices. Each job set is disjoint; no job
SHALL be represented in more than one MIB job set.
Monitor: Short for Job Monitoring Application.
Page: A page is a logical division of the original source document.
Number up is the imposition of more than one page on a single side of a
sheet. See "impression" and "sheet" and "two-up".
Proxy: An agent that acts as a concentrator for one or more other
agents by accepting SNMP operations on the behalf of one or more other
agents, forwarding them on to those other agents, gathering responses
from those other agents and returning them to the original requesting
monitor.
Queuing: The act of a device or server of ordering (queuing) the jobs
for the purposes of scheduling the jobs to be processed.
Printer: A device that puts marks on media.
Server: A network entity that accepts jobs from clients and in turn
submits the jobs to printers and other devices that may be directly
connected to the server via a serial or parallel port or may be on the
network. A server MAY be a printer supervisor control program, or a
print spooler.
Sheet: A sheet is a single instance of a medium, whether printing on
one or both sides of the medium. See "impression" and "page".
Bergman, Hastings, Isaacson, Lewis Informational [Page 11]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
SNMP Information Object: A name, value-pair that specifies an action,
a status, or a condition in an SNMP MIB. Objects are identified in
SNMP by an OBJECT IDENTIFIER.
Spooler: A server that accepts jobs, spools the data, and decides when
and on which printer to print the job. A spooler is a client to a
printer or a printer supervisor, depending on implementation.
Spooling: The act of a device or server of (1) accepting jobs and (2)
writing the job's attributes and document data on to secondary storage.
Stacked: When a media sheet is placed in an output bin of a device.
Supervisor: A server that contains a control program that controls a
printer or other device. A supervisor is a client to the printer or
other device.
System Operator: A user that uses a monitor to monitor the system and
carries out tasks to keep the system running.
System Administrator: A user that specifies policy for the system.
Two-up: The placement of two pages on one side of a sheet so that each
side or impressions counts as two pages. See "page" and "sheet".
User: A person that uses a client or a monitor. See "end user".
2.1 System Configurations for the Job Monitoring MIB
This section enumerates the three configurations in which the Job
Monitoring MIB is intended to be used. To simplify the pictures, the
devices are shown as printers. See section 1.1 entitled "Types of
Information in the MIB".
The diagram in the Printer MIB[print-mib] entitled: "One Printer's View
of the Network" is assumed for this MIB as well. Please refer to that
diagram to aid in understanding the following system configurations.
2.1.1 Configuration 1 - client-printer
In the client-printer configuration 1, the client(s) submit jobs
directly to the printer, either by some direct connect, or by network
connection.
The job submitting client and/or monitoring application monitor jobs by
communicating directly with an agent that is part of the printer. The
agent in the printer SHALL keep the job in the Job Monitoring MIB as
long as the job is in the printer, plus a defined time period after the
job enters the completed state in which accounting programs can copy
out the accounting data from the Job Monitoring MIB.

Figure 2-1 - Configuration 1 - client-printer - agent in the printer
The Job Monitoring MIB is designed to support the following
relationships (not shown in Figure 2-1):
1. Multiple clients MAY submit jobs to a printer.
2. Multiple clients MAY monitor a printer.
3. Multiple monitors MAY monitor a printer.
4. A client MAY submit jobs to multiple printers.
5. A monitor MAY monitor multiple printers.
2.1.2 Configuration 2 - client-server-printer - agent in the server
In the client-server-printer configuration 2, the client(s) submit jobs
to an intermediate server by some network connection, not directly to
the printer. While configuration 2 is included, the design center for
this MIB is configurations 1 and 3.
The job submitting client and/or monitoring application monitor jobs by
communicating directly with:
A Job Monitoring MIB agent that is part of the server (or a front
for the server)
There is no SNMP Job Monitoring MIB agent in the printer in
configuration 2, at least that the client or monitor are aware. In
this configuration, the agent SHALL return the current values of the
objects in the Job Monitoring MIB both for jobs the server keeps and
jobs that the server has submitted to the printer. The Job Monitoring
MIB agent obtains the required information from the printer by a method
that is beyond the scope of this document. The agent in the server
SHALL keep the job in the Job Monitoring MIB in the server as long as
the job is in the printer, plus a defined time period after the job
enters the completed state in which accounting programs can copy out
the accounting data from the Job Monitoring MIB.

The Job Monitoring MIB is designed to support the following
relationships (not shown in Figure 2-2):
1. Multiple clients MAY submit jobs to a server.
2. Multiple clients MAY monitor a server.
3. Multiple monitors MAY monitor a server.
4. A client MAY submit jobs to multiple servers.
5. A monitor MAY monitor multiple servers.
6. Multiple servers MAY submit jobs to a printer.
7. Multiple servers MAY control a printer.
2.1.3 Configuration 3 - client-server-printer - client monitors printer
agent and server
In the client-server-printer configuration 3, the client(s) submit jobs
to an intermediate server by some network connection, not directly to
the printer. That server does not contain a Job Monitoring MIB agent.
The job submitting client and/or monitoring application monitor jobs by
communicating directly with:
1. The server using some undefined protocol to monitor jobs in the
server (that does not contain the Job Monitoring MIB) AND
2. A Job Monitoring MIB agent that is part of the printer to
monitor jobs after the server passes the jobs to the printer.
Bergman, Hastings, Isaacson, Lewis Informational [Page 14]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
In such configurations, the server deletes its copy of the job
from the server after submitting the job to the printer usually
almost immediately (before the job does much processing, if
any).
In configuration 3, the agent (in the printer) SHALL keep the values of
the objects in the Job Monitoring MIB that the agent implements updated
for a job that the server has submitted to the printer. The agent
SHALL obtain information about the jobs submitted to the printer from
the server (either in the job submission protocol, in the document
data, or by direct query of the server), in order to populate some of
the objects the Job Monitoring MIB in the printer. The agent in the
printer SHALL keep the job in the Job Monitoring MIB as long as the job
is in the Printer, and longer in order to implement the completed state
in which monitoring programs can copy out the accounting data from the
Job Monitoring MIB.

In order to achieve interoperability between job monitoring
applications and job monitoring agents, this specification includes the
conformance requirements for both monitoring applications and agents.
3.1.1 Conformance Terminology
This specification uses the verbs: "SHALL", "SHOULD", "MAY", and "NEED
NOT" to specify conformance requirements according to RFC 2119
[RFC2119] as follows:
"SHALL": indicates an action that the subject of the sentence must
implement in order to claim conformance to this specification
"MAY": indicates an action that the subject of the sentence does not
have to implement in order to claim conformance to this
specification, in other words that action is an implementation option
"NEED NOT": indicates an action that the subject of the sentence
does not have to implement in order to claim conformance to this
specification. The verb "NEED NOT" is used instead of "may not",
since "may not" sounds like a prohibition.
"SHOULD": indicates an action that is recommended for the subject of
the sentence to implement, but is not required, in order to claim
conformance to this specification.
3.1.2 Agent Conformance Requirements
A conforming agent:
1. SHALL implement all MANDATORY groups in this specification.
2. SHALL implement any attributes if (1) the server or device
supports the functionality represented by the attribute and (2)
the information is available to the agent.
3. SHOULD implement both forms of an attribute if it implements an
attribute that permits a choice of INTEGER and OCTET STRING
forms, since implementing both forms may help management
applications by giving them a choice of representations, since
the representation are equivalent. See the JmAttributeTypeTC
textual-convention.
NOTE - This MIB, like the Printer MIB, is written following the subset
of SMIv2 that can be supported by SMIv1 and SNMPv1 implementations.
Bergman, Hastings, Isaacson, Lewis Informational [Page 16]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.1.2.1 MIB II System Group objects
The Job Monitoring MIB agent SHALL implement all objects in the System
Group of MIB-II[mib-II], whether the Printer MIB[print-mib] is
implemented or not.
3.1.2.2 MIB II Interface Group objects
The Job Monitoring MIB agent SHALL implement all objects in the
Interfaces Group of MIB-II[mib-II], whether the Printer MIB[print-mib]
is implemented or not.
3.1.2.3 Printer MIB objects
If the agent is providing access to a device that is a printer, the
agent SHALL implement all of the MANDATORY objects in the Printer
MIB[print-mib] and all the objects in other MIBs that conformance to
the Printer MIB requires, such as the Host Resources MIB[hr-mib]. If
the agent is providing access to a server that controls one or more
direct-connect or networked printers, the agent NEED NOT implement the
Printer MIB and NEED NOT implement the Host Resources MIB.
3.1.3 Job Monitoring Application Conformance Requirements
A conforming job monitoring application:
1. SHALL accept the full syntactic range for all objects in all
MANDATORY groups and all MANDATORY attributes that are required
to be implemented by an agent according to Section 3.1.2 and
SHALL either present them to the user or ignore them.
2. SHALL accept the full syntactic range for all attributes,
including enum and bit values specified in this specification
and additional ones that may be registered with the PWG and
SHALL either present them to the user or ignore them. In
particular, a conforming job monitoring application SHALL not
malfunction when receiving any standard or registered enum or
bit values. See Section 3.7 entitled "IANA and PWG
Registration Considerations".
3. SHALL NOT fail when operating with agents that materialize
attributes after the job has been submitted, as opposed to when
the job is submitted.
4. SHALL, if it supports a time attribute, accept either form of
the time attribute, since agents are free to implement either
time form.
Bergman, Hastings, Isaacson, Lewis Informational [Page 17]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.2 The Job Tables and the Oldest Active and Newest Active Indexes
The jmJobTable and jmAttributeTable contain objects and attributes,
respectively, for each job in a job set. These first two indexes are:
1. jmGeneralJobSetIndex - which job set
2. jmJobIndex - which job in the job set
In order for a monitoring application to quickly find that active jobs
(jobs in the pending, processing, or processingStopped states), the MIB
contains two indexes:
1. jmGeneralOldestActiveJobIndex - the index of the active job
that has been in the tables the longest.
2. jmGeneralNewestActiveJobIndex - the index of the active job
that has been most recently added to the tables.
The agent SHALL assign the next incremental value of jmJobIndex to the
job, when a new job is accepted by the server or device to which the
agent is providing access. If the incremented value of jmJobIndex
would exceed the implementation-defined maximum value for jmJobIndex,
the agent SHALL 'wrap' back to 1. An agent uses the resulting value of
jmJobIndex for storing information in the jmJobTable and the
jmAttributeTable about the job.
It is recommended that the largest value for jmJobIndex be much larger
than the maximum number of jobs that the implementation can contain at
a single time, so as to minimize the premature re-use of a jmJobIndex
value for a newer job while clients retain the same 'stale' value for
an older job.
It is recommended that agents that are providing access to
servers/devices that already allocate job-identifiers for jobs as
integers use the same integer value for the jmJobIndex. Then
management applications using this MIB and applications using other
protocols will see the same job identifiers for the same jobs. Agents
providing access to systems that contain jobs with a job identifier of
0 SHALL map the job identifier value 0 to a jmJobIndex value that is
one higher than the highest job identifier value that any job can have
on that system. Then only job 0 will have a different job-identifier
value than the job's jmJobIndex value.
NOTE - If a server or device accepts jobs using multiple job submission
protocols, it may be difficult for the agent to meet the recommendation
to use the job-identifier values that the server or device assigns as
the jmJobIndex value, unless the server/device assigns job-identifiers
for each of its job submission protocols from the same job-identifier
number space.
Bergman, Hastings, Isaacson, Lewis Informational [Page 18]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
Each time a new job is accepted by the server or device that the agent
is providing access to AND that job is to be 'active' (pending,
processing, or processingStopped, but not pendingHeld), the agent SHALL
copy the value of the job's jmJobIndex to the
jmGeneralNewestActiveJobIndex object. If the new job is to be
'inactive' (pendingHeld state), the agent SHALL not change the value of
jmGeneralNewestActiveJobIndex object (though the agent SHALL assign the
next incremental jmJobIndex value to the job).
When a job transitions from one of the 'active' job states (pending,
processing, processingStopped) to one of the 'inactive' job states
(pendingHeld, completed, canceled, or aborted), with a jmJobIndex value
that matches the jmGeneralOldestActiveJobIndex object, the agent SHALL
advance (or wrap) the value to the next oldest 'active' job, if any.
See the JmJobStateTC textual-convention for a definition of the job
states.
Whenever a job transitions from one of the 'inactive' job states to one
of the 'active' job states (from pendingHeld to pending or processing),
the agent SHALL update the value of either the
jmGeneralOldestActiveJobIndex or the jmGeneralNewestActiveJobIndex
objects, or both, if the job's jmJobIndex value is outside the range
between jmGeneralOldestActiveJobIndex and
jmGeneralNewestActiveJobIndex.
When all jobs become 'inactive', i.e., enter the pendingHeld,
completed, canceled, or aborted states, the agent SHALL set the value
of both the jmGeneralOldestActiveJobIndex and
jmGeneralNewestActiveJobIndex objects to 0.
NOTE - Applications that wish to efficiently access all of the active
jobs MAY use jmGeneralOldestActiveJobIndex value to start with the
oldest active job and continue until they reach the index value equal
to jmGeneralNewestActiveJobIndex, skipping over any pendingHeld,
completed, canceled, or aborted jobs that might intervene.
If an application detects that the jmGeneralNewestActiveJobIndex is
smaller than jmGeneralOldestActiveJobIndex, the job index has wrapped.
In this case, the application SHALL reset the index to 1 when the end
of the table is reached and continue the GetNext operations to find the
rest of the active jobs.
NOTE - Applications detect the end of the jmAttributeTable table when
the OID returned by the GetNext operation is an OID in a different MIB.
There is no object in this MIB that specifies the maximum value for the
jmJobIndex supported by the implementation.
When the server or device is power-cycled, the agent SHALL remember the
next jmJobIndex value to be assigned, so that new jobs are not assigned
the same jmJobIndex as recent jobs before the power cycle.
Bergman, Hastings, Isaacson, Lewis Informational [Page 19]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.3 The Attribute Mechanism and the Attribute Table(s)
Attributes are similar to information objects, except that attributes
are identified by an enum, instead of an OID, so that attributes may be
registered without requiring a new MIB. Also an implementation that
does not have the functionality represented by the attribute can omit
the attribute entirely, rather than having to return a distinguished
value. The agent is free to materialize an attribute in the
jmAttributeTable as soon as the agent is aware of the value of the
attribute.
The agent materializes job attributes in a four-indexed
jmAttributeTable:
1. jmGeneralJobSetIndex - which job set
2. jmJobIndex - which job in the job set
3. jmAttributeTypeIndex - which attribute
4. jmAttributeInstanceIndex - which attribute instance for those
attributes that can have multiple values per job.
Some attributes represent information about a job, such as a file-name,
a document-name, a submission-time or a completion time. Other
attributes represent resources required, e.g., a medium or a colorant,
etc. to process the job before the job starts processing OR to indicate
the amount of the resource consumed during and after processing, e.g.,
pages completed or impressions completed. If both a required and a
consumed value of a resource is needed, this specification assigns two
separate attribute enums in the textual convention.
NOTE - The table of contents lists all the attributes in order. This
order is the order of enum assignments which is the order that the SNMP
GetNext operation returns attributes. Most attributes apply to all
three configurations covered by this MIB specification (see section 2.1
entitled "System Configurations for the Job Monitoring MIB"). Those
attributes that apply to a particular configuration are indicated as
'Configuration n:' and SHALL NOT be used with other configurations.
3.3.1 Conformance of Attribute Implementation
An agent SHALL implement any attribute if (1) the server or device
supports the functionality represented by the attribute and (2) the
information is available to the agent. The agent MAY create the
attribute row in the jmAttributeTable when the information is available
or MAY create the row earlier with the designated 'unknown' value
appropriate for that attribute. See next section.
If the server or device does not implement or does not provide access
to the information about an attribute, the agent SHOULD NOT create the
corresponding row in the jmAttributeTable.
Bergman, Hastings, Isaacson, Lewis Informational [Page 20]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.3.2 Useful, 'Unknown', and 'Other' Values for Objects and Attributes
Some attributes have a 'useful' Integer32 value, some have a 'useful'
OCTET STRING value, some MAY have either or both depending on
implementation, and some MUST have both. See the JmAttributeTypeTC
textual convention for the specification of each attribute.
SNMP requires that if an object cannot be implemented because its
values cannot be accessed, then a compliant agent SHALL return an SNMP
error in SNMPv1 or an exception value in SNMPv2. However, this MIB has
been designed so that 'all' objects can and SHALL be implemented by an
agent, so that neither the SNMPv1 error nor the SNMPv2 exception value
SHALL be generated by the agent. This MIB has also been designed so
that when an agent materializes an attribute, the agent SHALL
materialize a row consisting of both the jmAttributeValueAsInteger and
jmAttributeValueAsOctets objects.
In general, values for objects and attributes have been chosen so that
a management application will be able to determine whether a 'useful',
'unknown', or 'other' value is available. When a useful value is not
available for an object, that agent SHALL return a zero-length string
for octet strings, the value 'unknown(2)' for enums, a '0' value for an
object that represents an index in another table, and a value '-2' for
counting integers.
Since each attribute is represented by a row consisting of both the
jmAttributeValueAsInteger and jmAttributeValueAsOctets MANDATORY
objects, SNMP requires that the agent SHALL always create an attribute
row with both objects specified. However, for most attributes the
agent SHALL return a "useful" value for one of the objects and SHALL
return the 'other' value for the other object. For integer only
attributes, the agent SHALL always return a zero-length string value
for the jmAttributeValueAsOctets object. For octet string only
attributes, the agent SHALL always return a '-1' value for the
jmAttributeValueAsInteger object.
3.3.3 Index Value Attributes
A number of attributes are indexes in other tables. Such attribute
names end with the word 'Index'. If the agent has not (yet) assigned
an index value for a particular index attribute for a job, the agent
SHALL either: (1) return the value 0 or (2) not add this attribute to
the jmAttributeTable until the index value is assigned. In the
interests of brevity, the semantics for 0 is specified once here and is
not repeated for each index attribute specification and a DEFVAL of 0
is implied, even though the DEFVAL for jmAttributeValueAsInteger is -2.
Bergman, Hastings, Isaacson, Lewis Informational [Page 21]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.3.4 Data Sub-types and Attribute Naming Conventions
Many attributes are sub-typed to give a more specific data type than
Integer32 or OCTET STRING. The data sub-type of each attribute is
indicated on the first line(s) of the description. Some attributes
have several different data sub-type representations. When an
attribute has both an Integer32 data sub-type and an OCTET STRING data
sub-type, the attribute can be represented in a single row in the
jmAttributeTable. In this case, the data sub-type name is not included
as the last part of the name of the attribute, e.g., documentFormat(38)
which is both an enum and/or a name. When the data sub-types cannot be
represented by a single row in the jmAttributeTable, each such
representation is considered a separate attribute and is assigned a
separate name and enum value. For these attributes, the name of the
data sub-type is the last part of the name of the attribute: Name,
Index, DateAndTime, TimeStamp, etc. For example,
documentFormatIndex(37) is an index.
NOTE: The Table of Contents also lists the data sub-type and/or data
sub-types of each attribute, using the textual-convention name when
such is defined. The following abbreviations are used in the Table of
Contents as shown:
'Int32(-2..)' Integer32 (-2..2147483647)
'Int32(0..)' Integer32 (0..2147483647)
'Int32(1..)' Integer32 (1..2147483647)
'Int32(m..n)' For all other Integer ranges, the lower
and upper bound of the range is
indicated.
'UTF8String63' JmUTF8StringTC (SIZE(0..63))
'JobString63' JmJobStringTC (SIZE(0..63))
'Octets63' OCTET STRING (SIZE(0..63))
'Octets(m..n)' For all other OCTET STRING ranges, the
exact range is indicated.
Bergman, Hastings, Isaacson, Lewis Informational [Page 22]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.3.5 Single-Value (Row) Versus Multi-Value (MULTI-ROW) Attributes
Most attributes have only one row per job. However, a few attributes
can have multiple values per job or even per document, where each value
is a separate row in the jmAttributeTable. Unless indicated with
'MULTI-ROW:' in the JmAttributeTypeTC description, an agent SHALL
ensure that each attribute occurs only once in the jmAttributeTable for
a job. Most of the 'MULTI-ROW' attributes do not allow duplicate
values, i.e., the agent SHALL ensure that each value occurs only once
for a job. Only if the specification of the 'MULTI-ROW' attribute also
says "There is no restriction on the same xxx occurring in multiple
rows" can the agent allow duplicate values to occur for the job.
NOTE - Duplicates are allowed for 'extensive' 'MULTI-ROW' attributes,
such as fileName(34) or documentName(35) which are specified to be
'per-document' attributes, but are not allowed for 'intensive' 'MULTI-
ROW' attributes, such as mediumConsumed(171) and documentFormat(38)
which are specified to be 'per-job' attributes.
3.3.6 Requested Objects and Attributes
A number of objects and attributes record requirements for the job.
Such object and attribute names end with the word 'Requested'. In the
interests of brevity, the phrase 'requested' means: (1) requested by
the client (or intervening server) in the job submission protocol and
may also mean (2) embedded in the submitted document data, and/or (3)
defaulted by the recipient device or server with the same semantics as
if the requester had supplied, depending on implementation. Also if a
value is supplied by the job submission client, and the server/device
determines a better value, through processing or other means, the agent
MAY return that better value for such object and attribute.
3.3.7 Consumption Attributes
A number of objects and attributes record consumption. Such attribute
names end with the word 'Completed' or 'Consumed'. If the job has not
yet consumed what that resource is metering, the agent either: (1)
SHALL return the value 0 or (2) SHALL not add this attribute to the
jmAttributeTable until the consumption begins. In the interests of
brevity, the semantics for 0 is specified once here and is not repeated
for each consumption attribute specification and a DEFVAL of 0 is
implied, even though the DEFVAL for jmAttributeValueAsInteger is -2.
Bergman, Hastings, Isaacson, Lewis Informational [Page 23]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.3.8 Attribute Specifications
This section specifies the job attributes.
In the following definitions of the attributes, each description
indicates whether the useful value of the attribute SHALL be
represented using the jmAttributeValueAsInteger or the
jmAttributeValueAsOctets objects by the initial tag: 'INTEGER:' or
'OCTETS:', respectively.
Some attributes allow the agent implementer a choice of useful values
of either an integer, an octet string representation, or both,
depending on implementation. These attributes are indicated with
'INTEGER:' AND/OR 'OCTETS:' tags.
A very few attributes require both objects at the same time to
represent a pair of useful values (see mediumConsumed(171)). These
attributes are indicated with 'INTEGER:' AND 'OCTETS:' tags. See the
jmAttributeGroup for the descriptions of these two MANDATORY objects.
NOTE - The enum assignments are grouped logically with values assigned
in groups of 20, so that additional values may be registered in the
future and assigned a value that is part of their logical grouping.
Values in the range 2**30 to 2**31-1 are reserved for private or
experimental usage. This range corresponds to the same range reserved
in IPP. Implementers are warned that use of such values may conflict
with other implementations. Implementers are encouraged to request
registration of enum values following the procedures in Section 3.7.1.
NOTE: No attribute name exceeds 31 characters.

jobStateReasons2(3), JmJobStateReasons2TC
INTEGER: Additional information about the job's current
state that augments the jmJobState object. See the
description under the JmJobStateReasons1TC textual-
convention.
jobStateReasons3(4), JmJobStateReasons3TC
INTEGER: Additional information about the job's current

Bergman, Hastings, Isaacson, Lewis Informational [Page 25]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
processingMessage(6), JmUTF8StringTC (SIZE(0..63))
OCTETS: MULTI-ROW: A coded character set message that is
generated by the server or device during the processing of
the job as a simple form of processing log to show progress
and any problems. The natural language of each value is
specified by the corresponding
processingMessageNaturalLangTag(7) value.
NOTE - This attribute is intended for such conditions as
interpreter messages, rather than being the printable form
of the jmJobState and jmJobStateReasons1 objects and
jobStateReasons2, jobStateReasons3, and jobStateReasons4
attributes. In order to produce a localized printable form
of these job state objects/attribute, a management
application SHOULD produce a message from their enum and
bit values.
NOTE - There is no job description attribute in IPP/1.0
that corresponds to this attribute and this attribute does
not correspond to the IPP/1.0 'job-state-message' job
description attribute, which is just a printable form of
the IPP 'job-state' and 'job-state-reasons' job attributes.
There is no restriction for the same message occurring in
multiple rows.
processingMessageNaturalLangTag(7), OCTET STRING(SIZE(0..63))
OCTETS: MULTI-ROW: The natural language of the
corresponding processingMessage(6) attribute value. See
section 3.6.1, entitled 'Text generated by the server or
device'.
If the agent does not know the natural language of the job
processing message, the agent SHALL either (1) return a
zero length string value for the
processingMessageNaturalLangTag(7) attribute or (2) not
return the processingMessageNaturalLangTag(7) attribute for
the job.
There is no restriction for the same tag occurring in
multiple rows, since when this attribute is implemented, it
SHOULD have a value row for each corresponding
processingMessage(6) attribute value row.
Bergman, Hastings, Isaacson, Lewis Informational [Page 26]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
jobCodedCharSet(8), CodedCharSet
INTEGER: The MIBenum identifier of the coded character set
that the agent is using to represent coded character set
objects and attributes of type 'JmJobStringTC'. These
coded character set objects and attributes are either: (1)
supplied by the job submitting client or (2) defaulted by
the server or device when omitted by the job submitting
client. The agent SHALL represent these objects and
attributes in the MIB either (1) in the coded character set
as they were submitted or (2) MAY convert the coded
character set to another coded character set or encoding
scheme as identified by the jobCodedCharSet(8) attribute.
See section 3.6.2, entitled 'Text supplied by the job
submitter'.
These MIBenum values are assigned by IANA [IANA-charsets]
when the coded character sets are registered. The coded
character set SHALL be one of the ones registered with IANA
[IANA] and the enum value uses the CodedCharSet textual-
convention from the Printer MIB. See the JmJobStringTC
textual-convention.
If the agent does not know what coded character set was
used by the job submitting client, the agent SHALL either
(1) return the 'unknown(2)' value for the
jobCodedCharSet(8) attribute or (2) not return the
jobCodedCharSet(8) attribute for the job.
jobNaturalLanguageTag(9), OCTET STRING(SIZE(0..63))
OCTETS: The natural language of the job attributes supplied
by the job submitter or defaulted by the server or device
for the job, i.e., all objects and attributes represented
by the 'JmJobStringTC' textual-convention, such as jobName,
mediumRequested, etc. See Section 3.6.2, entitled 'Text
supplied by the job submitter'.
If the agent does not know what natural language was used
by the job submitting client, the agent SHALL either (1)
return a zero length string value for the
jobNaturalLanguageTag(9) attribute or (2) not return
jobNaturalLanguageTag(9) attribute for the job.
Bergman, Hastings, Isaacson, Lewis Informational [Page 27]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ Job Identification attributes (20 - 49 decimal)
+
+ The following attributes help an end user, a system
+ operator, or an accounting program identify a job.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
jobURI(20), OCTET STRING(SIZE(0..63))
OCTETS: MULTI-ROW: The job's Universal Resource
Identifier (URI) [RFC1738]. See IPP [ipp-model] for
example usage.
NOTE - The agent may be able to generate this value on each
SNMP Get operation from smaller values, rather than having
to store the entire URI.
If the URI exceeds 63 octets, the agent SHALL use multiple
values, with the next 63 octets coming in the second value,
etc.
NOTE - IPP [ipp-model] has a 1023-octet maximum length for
a URI, though the URI standard itself and HTTP/1.1 specify
no maximum length.
jobAccountName(21), OCTET STRING(SIZE(0..63))
OCTETS: Arbitrary binary information which MAY be coded
character set data or encrypted data supplied by the
submitting user for use by accounting services to allocate
or categorize charges for services provided, such as a
customer account name or number.
NOTE: This attribute NEED NOT be printable characters.
serverAssignedJobName(22), JmJobStringTC (SIZE(0..63))
OCTETS: Configuration 3 only: The human readable string
name, number, or ID of the job as assigned by the server
that submitted the job to the device that the agent is
providing access to with this MIB.
NOTE - This attribute is intended for enabling a user to
find his/her job that a server submitted to a device when
either the client does not support the jmJobSubmissionID or
the server does not pass the jmJobSubmissionID through to
the device.
Bergman, Hastings, Isaacson, Lewis Informational [Page 28]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
jobName(23), JmJobStringTC (SIZE(0..63))
OCTETS: The human readable string name of the job as
assigned by the submitting user to help the user
distinguish between his/her various jobs. This name does
not need to be unique.
This attribute is intended for enabling a user or the
user's application to convey a job name that MAY be printed
on a start sheet, returned in a query result, or used in
notification or logging messages.
In order to assist users to find their jobs for job
submission protocols that don't supply a jmJobSubmissionID,
the agent SHOULD maintain the jobName attribute for the
time specified by the jmGeneralJobPersistence object,
rather than the (shorter) jmGeneralAttributePersistence
object.
If this attribute is not specified when the job is
submitted, no job name is assumed, but implementation
specific defaults are allowed, such as the value of the
documentName attribute of the first document in the job or
the fileName attribute of the first document in the job.
The jobName attribute is distinguished from the jobComment
attribute, in that the jobName attribute is intended to
permit the submitting user to distinguish between different
jobs that he/she has submitted. The jobComment attribute
is intended to be free form additional information that a
user might wish to use to communicate with himself/herself,
such as a reminder of what to do with the results or to
indicate a different set of input parameters were tried in
several different job submissions.
Bergman, Hastings, Isaacson, Lewis Informational [Page 29]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
jobServiceTypes(24), JmJobServiceTypesTC
INTEGER: Specifies the type(s) of service to which the job
has been submitted (print, fax, scan, etc.). The service
type is bit encoded with each job service type so that more
general and arbitrary services can be created, such as
services with more than one destination type, or ones with
only a source or only a destination. For example, a job
service might scan, faxOut, and print a single job. In
this case, three bits would be set in the jobServiceTypes
attribute, corresponding to the hexadecimal values: 0x8 +
0x20 + 0x4, respectively, yielding: 0x2C.
Whether this attribute is set from a job attribute supplied
by the job submission client or is set by the recipient job
submission server or device depends on the job submission
protocol. This attribute SHALL be implemented if the
server or device has other types in addition to or instead
of printing.
One of the purposes of this attribute is to permit a
requester to filter out jobs that are not of interest. For
example, a printer operator may only be interested in jobs
that include printing.
jobSourceChannelIndex(25), Integer32 (0..2147483647)
INTEGER: The index of the row in the associated Printer
MIB[print-mib] of the channel which is the source of the
print job.
jobSourcePlatformType(26), JmJobSourcePlatformTypeTC
INTEGER: The source platform type of the immediate
upstream submitter that submitted the job to the server
(configuration 2) or device (configuration 1 and 3) to
which the agent is providing access. For configuration 1,
this is the type of the client that submitted the job to
the device; for configuration 2, this is the type of the
client that submitted the job to the server; and for
configuration 3, this is the type of the server that
submitted the job to the device.
submittingServerName(27), JmJobStringTC (SIZE(0..63))
OCTETS: For configuration 3 only: The administrative name
of the server that submitted the job to the device.
submittingApplicationName(28), JmJobStringTC (SIZE(0..63))
OCTETS: The name of the client application (not the server
in configuration 3) that submitted the job to the server or

jobKOctetsTransferred(94), Integer32 (-2..2147483647)
INTEGER: The number of K (1024) octets transferred to the
server or device to which the agent is providing access.
This count is independent of the number of copies of the
job or documents that will be produced, but it is only a
measure of the number of bytes transferred to the server or
device.
The agent SHALL round the actual number of octets
transferred up to the next higher K. Thus 0 octets SHALL
be represented as '0', 1-1024 octets SHALL BE represented
as '1', 1025-2048 SHALL be '2', etc. When the job
completes, the values of the jmJobKOctetsPerCopyRequested
object and the jobKOctetsTransferred attribute SHALL be
equal.
NOTE - The jobKOctetsTransferred can be used with the
jmJobKOctetsPerCopyRequested object in order to produce a
relative indication of the progress of the job for agents
that do not implement the jmJobKOctetsProcessed object.
sheetCompletedCopyNumber(95), Integer32 (-2..2147483647)
INTEGER: The number of the copy being stacked for the
current document. This number starts at 0, is set to 1
when the first sheet of the first copy for each document is
being stacked and is equal to n where n is the nth sheet
stacked in the current document copy. See section 3.4 ,
entitled 'Monitoring Job Progress'.
sheetCompletedDocumentNumber(96), Integer32 (-2..2147483647)
INTEGER: The ordinal number of the document in the job
that is currently being stacked. This number starts at 0,
increments to 1 when the first sheet of the first document
in the job is being stacked, and is equal to n where n is

INTEGER: The number of full color impressions completed by
the device for this job so far. For printing, the
impressions completed includes interpreting, marking, and
stacking the output. For other types of job services, the
number of impressions completed includes the number of
impressions processed. Full color impressions are typically
defined as those requiring 3 or more colorants, but this
MAY vary by implementation. In any case, the value of this
attribute counts by 1 for each side that has full color,
not by the number of colors per side (and the other
impression counters are incremented, except
highlightColorImpressionsCompleted(115)).

3.3.9 Job State Reason bit definitions
The JmJobStateReasonsNTC (N=1..4) textual-conventions are used with the

to provide additional information regarding the current jmJobState
object value. These values MAY be used with any job state or states
for which the reason makes sense.
NOTE - While values cannot be added to the jmJobState object without
impacting deployed clients that take actions upon receiving jmJobState
values, it is the intent that additional JmJobStateReasonsNTC enums can
be defined and registered without impacting such deployed clients. In
other words, the jmJobStateReasons1 object and jobStateReasonsN
attributes are intended to be extensible.
NOTE - The Job Monitoring MIB contains a superset of the IPP
values[ipp-model] for the IPP 'job-state-reasons' attribute, since the
Job Monitoring MIB is intended to cover other job submission protocols
as well. Also some of the names of the reasons have been changed from
'printer' to 'device', since the Job Monitoring MIB is intended to
cover additional types of devices, including input devices, such as
scanners.

3.3.9.1 JmJobStateReasons1TC specification
The following standard values are defined (in hexadecimal) as powers of
two, since multiple values MAY be used at the same time. For ease of
understanding, the JmJobStateReasons1TC reasons are presented in the
order in which the reasons are likely to occur (if implemented),
starting with the 'jobIncoming' value and ending with the
'jobCompletedWithErrors' value.
other 0x1
The job state reason is not one of the standardized or
registered reasons.
unknown 0x2
The job state reason is not known to the agent or is
indeterminent.
jobIncoming 0x4
The job has been accepted by the server or device, but the
server or device is expecting (1) additional operations
from the client to finish creating the job and/or (2) is
accessing/accepting document data.
submissionInterrupted 0x8
The job was not completely submitted for some unforeseen
reason, such as: (1) the server has crashed before the job
was closed by the client, (2) the server or the document
transfer method has crashed in some non-recoverable way
before the document data was entirely transferred to the
server, (3) the client crashed or failed to close the job
before the time-out period.
jobOutgoing 0x10
Configuration 2 only: The server is transmitting the job
to the device.
jobHoldSpecified 0x20
The value of the job's jobHold(52) attribute is TRUE. The
job SHALL NOT be a candidate for processing until this
reason is removed and there are no other reasons to hold
the job.
jobHoldUntilSpecified 0x40
The value of the job's jobHoldUntil(53) attribute specifies
a time period that is still in the future. The job SHALL
NOT be a candidate for processing until this reason is
removed and there are no other reasons to hold the job.
Bergman, Hastings, Isaacson, Lewis Informational [Page 45]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
jobProcessAfterSpecified 0x80
The value of the job's jobProcessAfterDateAndTime(51)
attribute specifies a time that is still in the future.
The job SHALL NOT be a candidate for processing until this
reason is removed and there are no other reasons to hold
the job.
resourcesAreNotReady 0x100
At least one of the resources needed by the job, such as
media, fonts, resource objects, etc., is not ready on any
of the physical devices for which the job is a candidate.
This condition MAY be detected when the job is accepted, or
subsequently while the job is pending or processing,
depending on implementation.
deviceStoppedPartly 0x200
One or more, but not all, of the devices to which the job
is assigned are stopped. If all of the devices are stopped
(or the only device is stopped), the deviceStopped reason
SHALL be used.
deviceStopped 0x400
The device(s) to which the job is assigned is (are all)
stopped.
jobInterpreting 0x800
The device to which the job is assigned is interpreting the
document data.
jobPrinting 0x1000
The output device to which the job is assigned is marking
media. This value is useful for servers and output devices
which spend a great deal of time processing (1) when no
marking is happening and then want to show that marking is
now happening or (2) when the job is in the process of
being canceled or aborted while the job remains in the
processing state, but the marking has not yet stopped so
that impression or sheet counts are still increasing for
the job.
jobCanceledByUser 0x2000
The job was canceled by the owner of the job, i.e., by a
user whose name is the same as the value of the job's
jmJobOwner object, or by some other authorized end-user,
such as a member of the job owner's security group.
jobCanceledByOperator 0x4000
The job was canceled by the operator, i.e., by a user who
has been authenticated as having operator privileges
(whether local or remote).
Bergman, Hastings, Isaacson, Lewis Informational [Page 46]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
jobCanceledAtDevice 0x8000
The job was canceled by an unidentified local user, i.e., a
user at a console at the device.
abortedBySystem 0x10000
The job (1) is in the process of being aborted, (2) has
been aborted by the system and placed in the 'aborted'
state, or (3) has been aborted by the system and placed in
the 'pendingHeld' state, so that a user or operator can
manually try the job again.
processingToStopPoint 0x20000
The requester has issued an operation to cancel or
interrupt the job or the server/device has aborted the job,
but the server/device is still performing some actions on
the job until a specified stop point occurs or job
termination/cleanup is completed.
This reason is recommended to be used in conjunction with
the processing job state to indicate that the server/device
is still performing some actions on the job while the job
remains in the processing state. After all the job's
resources consumed counters have stopped incrementing, the
server/device moves the job from the processing state to
the canceled or aborted job states.
serviceOffLine 0x40000
The service or document transform is off-line and accepting
no jobs. All pending jobs are put into the pendingHeld
state. This situation could be true if the service's or
document transform's input is impaired or broken.
jobCompletedSuccessfully 0x80000
The job completed successfully.
jobCompletedWithWarnings 0x100000
The job completed with warnings.
jobCompletedWithErrors 0x200000
The job completed with errors (and possibly warnings too).
Bergman, Hastings, Isaacson, Lewis Informational [Page 47]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
The following additional job state reasons have been added to represent
job states that are in ISO DPA[iso-dpa] and other job submission
protocols:
jobPaused 0x400000
The job has been indefinitely suspended by a client issuing
an operation to suspend the job so that other jobs may
proceed using the same devices. The client MAY issue an
operation to resume the paused job at any time, in which
case the agent SHALL remove the jobPaused values from the
job's jmJobStateReasons1 object and the job is eventually
resumed at or near the point where the job was paused.
jobInterrupted 0x800000
The job has been interrupted while processing by a client
issuing an operation that specifies another job to be run
instead of the current job. The server or device will
automatically resume the interrupted job when the
interrupting job completes.
jobRetained 0x1000000
The job is being retained by the server or device with all
of the job's document data (and submitted resources, such
as fonts, logos, and forms, if any). Thus a client could
issue an operation to the server or device to either (1)
re-do the job (or a copy of the job) on the same server or
device or (2) resubmit the job to another server or device.
When a client could no longer re-do/resubmit the job, such
as after the document data has been discarded, the agent
SHALL remove the jobRetained value from the
jmJobStateReasons1 object.
These bit definitions are the equivalent of a type 2 enum except that
combinations of bits may be used together. See section 3.7.1.2. The
remaining bits are reserved for future standardization and/or
registration.

INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
jobStartWaitTimeOut 0x100
The server/device has stopped the job at the beginning of
processing to await human action, such as installing a
special cartridge or special non-standard media, but the
job was not resumed within the site-settable time-out value
and the server/device has transitioned the job to the
pendingHeld state.
jobEndWaitTimeOut 0x200
The server/device has stopped the job at the end of
processing to await human action, such as removing a
special cartridge or restoring standard media, but the job
was not resumed within the site-settable time-out value and
the server/device has transitioned the job to the completed
state.
jobPasswordWaitTimeOut 0x400
The server/device has stopped the job at the beginning of
processing to await input of the job's password, but the
password was not received within the site-settable time-out
value.
deviceTimedOut 0x800
A device that the job was using has not responded in a
period specified by the device's site-settable attribute.
connectingToDeviceTimeOut 0x1000
The server is attempting to connect to one or more devices
which may be dial-up, polled, or queued, and so may be busy
with traffic from other systems, but server was unable to
connect to the device within the site-settable time-out
value.

ending normal processing.
Bergman, Hastings, Isaacson, Lewis Informational [Page 50]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
jobPasswordWait 0x20000
The server/device has selected the job to be next to
process, but instead of assigning resources and starting
the job processing, the server/device has transitioned the
job to the pendingHeld state to await entry of a password
(and dispatched another job, if there is one).
validating 0x40000
The server/device is validating the job after accepting the
job.
queueHeld 0x80000
The operator has held the entire job set or queue.
jobProofWait 0x100000
The job has produced a single proof copy and is in the
pendingHeld state waiting for the requester to issue an
operation to release the job to print normally, obeying any
job and document copy attributes that were originally
submitted.

The System Administrator settable device policy is (1) to
require PINs, and (2) to hold jobs that do not have a pin
supplied as an input parameter when the job was created.
exceededAccountLimit 0x2000000
The account for which this job is drawn has exceeded its
limit. This condition SHOULD be detected before the job is
scheduled so that the user does not wait until his/her job
is scheduled only to find that the account is overdrawn.
This condition MAY also occur while the job is processing
either as processing begins or part way through processing.
heldForRetry 0x4000000
The job encountered some errors that the server/device
could not recover from with its normal retry procedures,
but the error might not be encountered if the job is
processed again in the future. Example cases are phone
number busy or remote file system in-accessible. For such
a situation, the server/device SHALL transition the job
from the processing to the pendingHeld, rather than to the
aborted state.
Bergman, Hastings, Isaacson, Lewis Informational [Page 51]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
The following values are from the X/Open PSIS draft standard:
canceledByShutdown 0x8000000
The job was canceled because the server or device was
shutdown before completing the job.
deviceUnavailable 0x10000000
This job was aborted by the system because the device is
currently unable to accept jobs.
wrongDevice 0x20000000

unable to handle this particular job; the spooler SHOULD
try another device or the user should submit the job to
another device.
badJob 0x40000000
This job was aborted by the system because this job has a
major problem, such as an ill-formed PDL; the spooler
SHOULD not even try another device.
These bit definitions are the equivalent of a type 2 enum except that
combinations of them may be used together. See section 3.7.1.2.
3.3.9.3 JmJobStateReasons3TC specification
This textual-convention is used with the jobStateReasons3 attribute to
provides additional information regarding the jmJobState object. The
following standard values are defined (in hexadecimal) as powers of
two, since multiple values may be used at the same time:
jobInterruptedByDeviceFailure 0x1
A device or the print system software that the job was
using has failed while the job was processing. The server
or device is keeping the job in the pendingHeld state until
an operator can determine what to do with the job.

3.4 Monitoring Job Progress
There are a number of objects and attributes for monitoring the
progress of a job. These objects and attributes count the number of K
octets, impressions, sheets, and pages requested or completed. For
impressions and sheets, "completed" means stacked, unless the
implementation is unable to detect when each sheet is stacked, in which
case stacked is approximated when processing of each sheet completes.
There are objects and attributes for the overall job and for the
current copy of the document currently being stacked. For the latter,
the rate at which the various objects and attributes count depends on
the sheet and document collation of the job.
Job Collation included sheet collation and document collation. Sheet
collation is defined to be the ordering of sheets within a document
copy. Document collation is defined to be ordering of document copies
within a multi-document job. There are three types of job collation
(see terminology definitions in Section 2):
1.uncollatedSheets(3) - No collation of the sheets within each
document copy, i.e., each sheet of a document that is to
produce multiple copies is replicated before the next sheet in
the document is processed and stacked. If the device has an
output bin collator, the uncollatedSheets(3) value may actually
produce collated sheets as far as the user is concerned (in the
output bins). However, when the job collation is the
'uncollatedSheets(3)' value, job progress is indistinguishable
to a monitoring application between a device that has an output
bin collator and one that does not.
Bergman, Hastings, Isaacson, Lewis Informational [Page 53]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
2.collatedDocuments(4) - Collation of the sheets within each
document copy is performed within the printing device by making
multiple passes over either the source or an intermediate
representation of the document. In addition, when there are
multiple documents per job, the i'th copy of each document is
stacked before the j'th copy of each document, i.e., the
documents are collated within each job copy. For example, if a
job is submitted with documents, A and B, the job is made
available to the end user as: A, B, A, B, .... The
'collatedDocuments(4)' value corresponds to the IPP [ipp-model]
'separate-documents-collated-copies' value of the "multiple-
document-handling" attribute.
If jobCopiesRequested or documentCopiesRequested = 1, then
jobCollationType is defined as 4.
3.uncollatedDocuments(5) - Collation of the sheets within each
document copy is performed within the printing device by making
multiple passes over either the source or an intermediate
representation of the document. In addition, when there are
multiple documents per job, all copies of the first document in
the job are stacked before the any copied of the next document
in the job, i.e., the documents are uncollated within the job.
For example, if a job is submitted with documents, A and B, the
job is mad available to the end user as: A, A, ..., B, B, ....
The 'uncollatedDocuments(5)' value corresponds to the IPP [ipp-
model] 'separate-documents-uncollated-copies' value of the
"multiple-document-handling" attribute.
Consider the following four variables that are used to monitor the
progress of a job's impressions:
1.jmJobImpressionsCompleted - counts the total number of
impressions stacked for the job
2.impressionsCompletedCurrentCopy - counts the number of
impressions stacked for the current document copy
3.sheetCompletedCopyNumber - identifies the number of the copy
for the current document being stacked where the first copy is
1.
4.sheetCompletedDocumentNumber - identifies the current document
within the job that is being stacked where the first document
in a job is 1. NOTE: this attribute SHOULD NOT be implemented
for implementations that only support one document per job.
For each of the three types of job collation, a job with three copies
of two documents (1, 2), where each document consists of 3 impressions,
the four variables have the following values as each sheet is stacked
for one-sided printing:

3.5 Job Identification
There are a number of attributes that permit a user, operator or system
administrator to identify jobs of interest, such as jobURI, jobName,
jobOriginatingHost, etc. In addition, there is a jmJobSubmissionID
object that is a text string table index. Being a table index allows a
monitoring application to quickly locate and identify a particular job
of interest that was submitted from a particular client by the user
invoking the monitoring application without having to scan the entire
job table. The Job Monitoring MIB needs to provide for identification
of the job at both sides of the job submission process. The primary
identification point is the client side. The jmJobSubmissionID allows
the monitoring application to identify the job of interest from all the
jobs currently "known" by the server or device. The value of
jmJobSubmissionID can be assigned by either the client's local system
or a downstream server or device. The point of assignment depends on
the job submission protocol in use.
The server/device-side identifier, called the jmJobIndex object, SHALL
be assigned by the SNMP Job Monitoring MIB agent when the server or
device accepts the jobs from submitting clients. The jmJobIndex object
allows the interested party to obtain all objects desired that relate
Bergman, Hastings, Isaacson, Lewis Informational [Page 57]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
to a particular job. See Section 3.2, entitled 'The Job Tables and the
Oldest Active and Newest Active Indexes' for the specification of how
the agent SHALL assign the jmJobIndex values.
The MIB provides a mapping table that maps each jmJobSubmissionID value
to a corresponding jmJobIndex value generated by the agent, so that an
application can determine the correct value for the jmJobIndex value
for the job of interest in a single Get operation, given the Job
Submission ID. See the jmJobIDGroup.
In some configurations there may be more than one application program
that monitors the same job when the job passes from one network entity
to another when it is submitted. See configuration 3. When there are
multiple job submission IDs, each entity MAY supply an appropriate
jmJobSubmissionID value. In this case there would be a separate entry
in the jmJobSubmissionID table, one for each jmJobSubmissionID. All
entries would map to the same jmJobIndex that contains the job data.
When the job is deleted, it is up to the agent to remove all entries
that point to the job from the jmJobSubmissionID table as well.
The jobName attribute provides a name that the user supplies as a job
attribute with the job. The jobName attribute is not necessarily
unique, even for one user, let alone across users.
3.5.1 The Job Submission ID specifications
This section specifies the formats for each of the registered Job
Submission Ids. This format is used by the JmJobSubmissionIDTypeTC.
Each job submission ID is a fixed-length, 48-octet printable US-ASCII
[US-ASCII] coded character string containing no control characters,
consisting of the following fields:
octet 1: The format letter identifying the format. The US-
ASCII characters '0-9', 'A-Z', and 'a-z' are assigned in
order giving 62 possible formats.
octets 2-40: A 39-character, US-ASCII trailing SPACE filled
field specified by the format letter, if the data is less
than 39 ASCII characters.
octets 41-48: A sequential or random US-ASCII number to make
the ID quasi-unique.
If the client does not supply a job submission ID in the job submission
protocol, then the agent SHALL assign a job submission ID using any of
the standard formats that are reserved for the agent. Clients SHALL
not use formats that are reserved for agents and agents SHALL NOT use
formats that are reserved for clients, in order to reduce conflicts in
ID generation. See the description for which formats are reserved for
clients or for agents.
Bergman, Hastings, Isaacson, Lewis Informational [Page 58]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999

octets 41-48: The US-ASCII 8-decimal-digit leading zero
representation of the jmJobIndex assigned by the agent.
This format is reserved for agents, since the agent supplies
octets 41-48, though the client supplies the file name.
'G' IPDS on the OS/400 platform
octets 2-40: Contains bytes 2-36 of the XOH Define Group
Boundary Group ID triplet. Octet position 2 MUST carry the
value x'03'. Bytes 37-40 MUST be filled with spaces.
octets 41-48: The US-ASCII 8-decimal-digit leading zero
representation of the jmJobIndex assigned by the agent.
This format is reserved for agents, since the agent supplies
octets 41-48, though the client supplies the job name.
NOTE - the job submission id is only intended to be unique between a
limited set of clients for a limited duration of time, namely, for the
life time of the job in the context of the server or device that is
processing the job. Some of the formats include something that is
unique per client and a random number so that the same job submitted by
the same client will have a different job submission id. For other
formats, where part of the id is guaranteed to be unique for each
client, such as the MAC address or URL, a sequential number SHOULD
suffice for each client (and may be easier for each client to manage).
Therefore, the length of the job submission id has been selected to
reduce the probability of collision to an extremely low number, but is
not intended to be an absolute guarantee of uniqueness. None-the-less,
collisions are remotely possible, but without bad consequences, since
this MIB is intended to be used only for monitoring jobs, not for
controlling and managing them.
Bergman, Hastings, Isaacson, Lewis Informational [Page 62]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.6 Internationalization Considerations
This section describes the internationalization considerations included
in this MIB.
3.6.1 Text generated by the server or device
There are a few objects and attributes generated by the server or
device that SHALL be represented using the Universal Multiple-Octet
Coded Character Set (UCS) [ISO-10646]. These objects and attributes
are always supplied (if implemented) by the agent, not by the job
submitting client:
1. jmGeneralJobSetName object
2. processingMessage(6) attribute
3. physicalDevice(32) (name value) attribute
The character encoding scheme for representing these objects and
attributes SHALL be UTF-8 as REQUIRED by RFC 2277 [RFC2277]. The
'JmUTF8StringTC' textual convention is used to indicate UTF-8 text
strings.
NOTE - For strings in 7-bit US-ASCII, there is no impact since the UTF-
8 representation of 7-bit ASCII is identical to the US-ASCII [US-ASCII]
encoding.
The text contained in the processingMessage(6) attribute is generated
by the server/device. The natural language for the
processingMessage(6) attribute is identified by the
processingMessageNaturalLangTag(7) attribute. The
processingMessageNaturalLangTag(7) attribute uses the
JmNaturalLanguageTagTC textual convention which SHALL conform to the
language tag mechanism specified in RFC 1766 [RFC1766]. The
JmNaturalLanguageTagTC value is the same as the IPP [IPP-model]
'naturalLanguage' attribute syntax. RFC 1766 specifies that a US-ASCII
string consisting of the natural language followed by an optional
country field. Both fields use the same two-character codes from ISO
639 [ISO-639] and ISO 3166 [ISO-3166], respectively, that are used in
the Printer MIB for identifying language and country.
Examples of the values of the processingMessageNaturalLangTag(7)
attribute include:
1. 'en' for English
2. 'en-us' for US English
3. 'fr' for French
4. 'de' for German
Bergman, Hastings, Isaacson, Lewis Informational [Page 63]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.6.2 Text supplied by the job submitter
All of the objects and attributes represented by the 'JmJobStringTC'
textual-convention are either (1) supplied in the job submission
protocol by the client that submits the job to the server or device or
(2) are defaulted by the server or device if the job submitting client
does not supply values. The agent SHALL represent these objects and
attributes in the MIB either (1) in the coded character set as they
were submitted or (2) MAY convert the coded character set to another
coded character set or encoding scheme. In any case, the resulting
coded character set representation SHOULD be UTF-8 [UTF-8], but SHALL
be one in which the code positions from 0 to 31 is not used, 32 to 127
is US-ASCII [US-ASCII], 127 is not unused, and the remaining code
positions 128 to 255 represent single-byte or multi-byte graphic
characters structured according to ISO 2022 [ISO-2022] or are unused.
The coded character set SHALL be one of the ones registered with IANA
[IANA] and SHALL be identified by the jobCodedCharSet attribute in the
jmJobAttributeTable for the job. If the agent does not know what coded
character set was used by the job submitting client, the agent SHALL
either (1) return the 'unknown(2)' value for the jobCodedCharSet
attribute or (2) not return the jobCodedCharSet attribute for the job.
Examples of coded character sets which meet this criteria for use as
the value of the jobCodedCharSet job attribute are: US-ASCII [US-
ASCII], ISO 8859-1 (Latin-1) [ISO-8859-1], any ISO 8859-n, HP Roman8,
IBM Code Page 850, Windows Default 8-bit set, UTF-8 [UTF-8], US-ASCII
plus JIS X0208-1990 Japanese [JIS X0208], US-ASCII plus GB2312-1980 PRC
Chinese [GB2312]. See the IANA registry of coded character sets [IANA
charsets].
Examples of coded character sets which do not meet this criteria are:
national 7-bit sets conforming to ISO 646 (except US-ASCII), EBCDIC,
and ISO 10646 (Unicode) [ISO-10646]. In order to represent Unicode
characters, the UTF-8 [UTF-8] encoding scheme SHALL be used which has
been assigned the MIBenum value of '106' by IANA.
The jobCodedCharSet attribute uses the imported 'CodedCharSet' textual-
convention from the Printer MIB [printmib].
The natural language for attributes represented by the textual-
convention JmJobStringTC is identified either (1) by the
jobNaturalLanguageTag(9) attribute or is keywords in US-English (as in
IPP). A monitoring application SHOULD attempt to localize keywords
into the language of the user by means of some lookup mechanism. If
the keyword value is not known to the monitoring application, the
monitoring application SHOULD assume that the value is in the natural
language specified by the job's jobNaturalLanguageTag(9) attribute and
SHOULD present the value to its user as is. The
Bergman, Hastings, Isaacson, Lewis Informational [Page 64]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
jobNaturalLanguageTag(9) attribute value SHALL have the same syntax and
semantics as the processingMessageNaturalLangTag(7) attribute, except
that the jobNaturalLanguageTag(9) attribute identifies the natural
language of attributes supplied by the job submitter instead of the
natural language of the processingMessage(6) attribute. See Section
3.6.1.
3.6.3 'DateAndTime' for representing the date and time
This MIB also contains objects that are represented using the
DateAndTime textual convention from SMIv2 [SMIv2-TC]. The job
management application SHALL display such objects in the locale of the
user running the monitoring application.
3.7 IANA and PWG Registration Considerations
This MIB does not require any additional registration schemes for IANA,
but does depend on registration schemes that other Internet standards
track specifications have set up. The names of these IANA registration
assignments under the /in-notes/iana/assignments/ path:
1.printer-language-numbers - used as enums in the documentFormat(38)
attribute
2.media-types - uses as keywords in the documentFormat(38) attribute
3.character-sets - used as enums in the jobCodedCharSet(8) attribute
The Printer Working Group (PWG) will handle registration of additional
enums after approving this standard, according to the procedures
described in this section:
3.7.1 PWG Registration of enums
This specification uses textual conventions to define enumerated values
(enums) and bit values. Enumerations (enums) and bit values are sets
of symbolic values defined for use with one or more objects or
attributes. All enumeration sets and bit value sets are assigned a
symbolic data type name (textual convention). As a convention the
symbolic name ends in "TC" for textual convention. These enumerations
are defined at the beginning of the MIB module specification.
The PWG has defined several type of enumerations for use in the Job
Monitoring MIB and the Printer MIB[print-mib]. These types differ in
the method employed to control the addition of new enumerations.
Throughout this document, references to "type n enum", where n can be
1, 2 or 3 can be found in the various tables. The definitions of these
types of enumerations are:
Bergman, Hastings, Isaacson, Lewis Informational [Page 65]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.7.1.1 Type 1 enumerations
Type 1 enumeration: All the values are defined in the Job Monitoring
MIB specification (RFC for the Job Monitoring MIB). Additional
enumerated values require a new RFC.
There are no type 1 enums in the current draft.
3.7.1.2 Type 2 enumerations
Type 2 enumeration: An initial set of values are defined in the Job
Monitoring MIB specification. Additional enumerated values are
registered with the PWG.
The following type 2 enums are contained in the current draft :
1. JmUTF8StringTC
2. JmJobStringTC
3. JmNaturalLanguageTagTC
4. JmTimeStampTC
5. JmFinishingTC [same enum values as IPP "finishing" attribute]
6. JmPrintQualityTC [same enum values as IPP "print-quality"
attribute]
7. JmTonerEconomyTC
8. JmMediumTypeTC
9. JmJobSubmissionIDTypeTC
10.JmJobCollationTypeTC
11.JmJobStateTC [same enum values as IPP "job-state" attribute]
12.JmAttributeTypeTC
For those textual conventions that have the same enum values as the
indicated IPP Job attribute are simultaneously registered by the PWG
for use with IPP [ipp-model] and the Job Monitoring MIB.
3.7.1.3 Type 3 enumeration
Type 3 enumeration: An initial set of values are defined in the Job
Monitoring MIB specification. Additional enumerated values are
registered through the PWG without PWG review.
There are no type 3 enums in the current draft.
Bergman, Hastings, Isaacson, Lewis Informational [Page 66]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.7.2 PWG Registration of type 2 bit values
This draft contains the following type 2 bit value textual-conventions:
1. JmJobServiceTypesTC
2. JmJobStateReasons1TC
3. JmJobStateReasons2TC
4. JmJobStateReasons3TC
5. JmJobStateReasons4TC
These textual-conventions are defined as bits in an Integer so that
they can be used with SNMPv1 SMI. The jobStateReasonsN (N=1..4)
attributes are defined as bit values using the corresponding
JmJobStateReasonsNTC textual-conventions.
The registration of JmJobServiceTypesTC and JmJobStateReasonsNTC bit
values follow the procedures for a type 2 enum as specified in Section
3.7.1.2.
3.7.3 PWG Registration of Job Submission Id Formats
In addition to enums and bit values, this specification assigns a
single ASCII digit or letter to various job submission ID formats. See
the JmJobSubmissionIDTypeTC textual-convention and the object. The
registration of JobSubmissionID format numbers follows the procedures
for a type 2 enum as specified in Section 3.7.1.2.
3.7.4 PWG Registration of MIME types/sub-types for document-formats
The documentFormat(38) attribute has MIME type/sub-type values for
indicating document formats which IANA registers as "media type" names.
The values of the documentFormat(38) attribute are the same as the
corresponding Internet Printing Protocol (IPP) "document-format" Job
attribute values [ipp-model].
3.8 Security Considerations
3.8.1 Read-Write objects
All objects are read-only, greatly simplifying the security
considerations. If another MIB augments this MIB, that MIB might
accept SNMP Write operations to objects in that MIB whose effect is to
modify the values of read-only objects in this MIB. However, that MIB
SHALL have to support the required access control in order to achieve
security, not this MIB.
Bergman, Hastings, Isaacson, Lewis Informational [Page 67]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
3.8.2 Read-Only Objects In Other User's Jobs
The security policy of some sites MAY be that unprivileged users can
only get the objects from jobs that they submitted, plus a few minimal
objects from other jobs, such as the jmJobKOctetsPerCopyRequested and
jmJobKOctetsProcessed objects, so that a user can tell how busy a
printer is. Other sites MAY allow all unprivileged users to see all
objects of all jobs. This MIB does not require, nor does it specify
how, such restrictions would be implemented. A monitoring application
SHOULD enforce the site security policy with respect to returning
information to an unprivileged end user that is using the monitoring
application to monitor jobs that do not belong to that user, i.e., the
jmJobOwner object in the jmJobTable does not match the user's user
name.
An operator is a privileged user that would be able to see all objects
of all jobs, independent of the policy for unprivileged users.
3.9 Notifications
This MIB does not specify any notifications. For simplicity,
management applications are expected to poll for status. The
jmGeneralJobPersistence and jmGeneralAttributePersistence objects
assist an application to determine the polling rate. The resulting
network traffic is not expected to be significant.
4 MIB specification
The following pages constitute the actual Job Monitoring MIB.

DESCRIPTION
"To facilitate internationalization, this TC represents
information using any coded character set registered by IANA as
specified in section 3.7. While it is recommended that the
coded character set be UTF-8 [UTF-8], the actual coded
character set SHALL be indicated by the value of the

JmTimeStampTC ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The simple time at which an event took place. The units are
in seconds since the system was booted.
NOTE - JmTimeStampTC is defined in units of seconds, rather
than 100ths of seconds, so as to be simpler for agents to
implement (even if they have to implement the 100ths of a
second to comply with implementing sysUpTime in MIB-II[mib-
II].)
NOTE - JmTimeStampTC is defined as an Integer32 so that it can
be used as a value of an attribute, i.e., as a value of the
jmAttributeValueAsInteger object. The TimeStamp textual-
convention defined in SNMPv2-TC [SMIv2-TC] is defined as an
APPLICATION 3 IMPLICIT INTEGER tag, not an Integer32 which is
defined in SNMPv2-SMI [SMIv2-TC] as UNIVERSAL 2 IMPLICIT

Figure 4 - Normal Job State Transitions
Normally a job progresses from left to right. Other state
transitions are unlikely, but are not forbidden. Not shown are
the transitions to the canceled state from the pending,
pendingHeld, and processingStopped states.
Jobs in the pending, processing, and processingStopped states
are called 'active', while jobs in the pendingHeld, canceled,
aborted, and completed states are called 'inactive'. Jobs
reach one of the three terminal states: completed, canceled, or
aborted, after the jobs have completed all activity, and all
MIB objects and attributes have reached their final values for
the job.
These values are the same as the enum values of the IPP 'job-
state' job attribute. See Section 3.7.1.2.
unknown(2),
The job state is not known, or its state is indeterminate.
pending(3),
The job is a candidate to start processing, but is not yet
processing.
pendingHeld(4),
The job is not a candidate for processing for any number of
reasons but will return to the pending state as soon as the
reasons are no longer present. The job's
jmJobStateReasons1 object and/or jobStateReasonsN (N=2..4)
attributes SHALL indicate why the job is no longer a
candidate for processing. The reasons are represented as
bits in the jmJobStateReasons1 object and/or
jobStateReasonsN (N=2..4) attributes. See the
Bergman, Hastings, Isaacson, Lewis Informational [Page 77]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
JmJobStateReasonsNTC (N=1..4) textual convention for the
specification of each reason.
processing(5),
One or more of:
1. the job is using, or is attempting to use, one or more
purely software processes that are analyzing, creating, or
interpreting a PDL, etc.,
2. the job is using, or is attempting to use, one or more
hardware devices that are interpreting a PDL, making marks
on a medium, and/or performing finishing, such as stapling,
etc., OR
3. (configuration 2) the server has made the job ready for
printing, but the output device is not yet printing it,
either because the job hasn't reached the output device or
because the job is queued in the output device or some
other spooler, awaiting the output device to print it.
When the job is in the processing state, the entire job
state includes the detailed status represented in the
device MIB indicated by the hrDeviceIndex value of the
job's physicalDevice attribute, if the agent implements
such a device MIB.
Implementations MAY, though they NEED NOT, include
additional values in the job's jmJobStateReasons1 object to
indicate the progress of the job, such as adding the
jobPrinting value to indicate when the device is actually
making marks on a medium and/or the processingToStopPoint
value to indicate that the server or device is in the
process of canceling or aborting the job.
processingStopped(6),
The job has stopped while processing for any number of
reasons and will return to the processing state as soon as
the reasons are no longer present.
The job's jmJobStateReasons1 object and/or the job's
jobStateReasonsN (N=2..4) attributes MAY indicate why the
job has stopped processing. For example, if the output
device is stopped, the deviceStopped value MAY be included
in the job's jmJobStateReasons1 object.
NOTE - When an output device is stopped, the device usually
indicates its condition in human readable form at the
device. The management application can obtain more
complete device status remotely by querying the appropriate
device MIB using the job's deviceIndex attribute(s), if the
agent implements such a device MIB
Bergman, Hastings, Isaacson, Lewis Informational [Page 78]
INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
canceled(7),
A client has canceled the job and the server or device has
completed canceling the job AND all MIB objects and
attributes have reached their final values for the job.
While the server or device is canceling the job, the job's
jmJobStateReasons1 object SHOULD contain the
processingToStopPoint value and one of the canceledByUser,
canceledByOperator, or canceledAtDevice values. The
canceledByUser, canceledByOperator, or canceledAtDevice
values remain while the job is in the canceled state.
aborted(8),
The job has been aborted by the system, usually while the
job was in the processing or processingStopped state and
the server or device has completed aborting the job AND all
MIB objects and attributes have reached their final values
for the job. While the server or device is aborting the
job, the job's jmJobStateReasons1 object MAY contain the
processingToStopPoint and abortedBySystem values. If
implemented, the abortedBySystem value SHALL remain while
the job is in the aborted state.
completed(9)
The job has completed successfully or with warnings or
errors after processing and all of the media have been
successfully stacked in the appropriate output bin(s) AND
all MIB objects and attributes have reached their final
values for the job. The job's jmJobStateReasons1 object
SHOULD contain one of: completedSuccessfully,
completedWithWarnings, or completedWithErrors values.
This is a type 2 enumeration. See Section 3.7.1.2."

JmJobServiceTypesTC ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Specifies the type(s) of service to which the job has been
submitted (print, fax, scan, etc.). The service type is
represented as an enum that is bit encoded with each job
service type so that more general and arbitrary services can be
created, such as services with more than one destination type,
or ones with only a source or only a destination. For example,
a job service might scan, faxOut, and print a single job. In
this case, three bits would be set in the jobServiceTypes
attribute, corresponding to the hexadecimal values: 0x8 + 0x20
+ 0x4, respectively, yielding: 0x2C.
Whether this attribute is set from a job attribute supplied by
the job submission client or is set by the recipient job
submission server or device depends on the job submission
protocol. With either implementation, the agent SHALL return a
non-zero value for this attribute indicating the type of the
job.
One of the purposes of this attribute is to permit a requester
to filter out jobs that are not of interest. For example, a
printer operator MAY only be interested in jobs that include
printing. That is why the attribute is in the job
identification category.
The following service component types are defined (in
hexadecimal) and are assigned a separate bit value for use with
the jobServiceTypes attribute:
other 0x1
The job contains some instructions that are not one of the
identified types.
unknown 0x2
The job contains some instructions whose type is unknown to
the agent.
print 0x4
The job contains some instructions that specify printing
scan 0x8
The job contains some instructions that specify scanning
Bergman, Hastings, Isaacson, Lewis Informational [Page 84]

mailList 0x100
The job contains some instructions that specify
distribution of documents using an electronic mail system.

See the JmJobSubmissionIDTypeTC textual convention. Each

If the requester (client or server) does not supply a job
submission ID in the job submission protocol, then the
recipient (server or device) SHALL assign a job submission ID
using any of the standard formats that have been reserved for
agents and adding the final 8 octets to distinguish the ID from
others submitted from the same requester.
The monitoring application, whether in the client or running
separately, MAY use the job submission ID to help identify
which jmJobIndex was assigned by the agent, i.e., in which row
the job information is in the other tables.
NOTE - fixed-length is used so that a management application
can use a shortened GetNext varbind (in SNMPv1 and SNMPv2) in
order to get the next submission ID, disregarding the remainder
of the ID in order to access jobs independent of the trailing
identifier part, e.g., to get all jobs submitted by a
particular jmJobOwner or submitted from a particular MAC

A monitoring application is able to copy this value to a
suitable longer term storage for later processing as part of an
accounting system.
Since the agent MAY add attributes representing resources to

5 Appendix A - Implementing the Job Life Cycle
The job object has well-defined states and client operations that
affect the transition between the job states. Internal server and
device actions also affect the transitions of the job between the job
states. These states and transitions are referred to as the job's life
cycle.
Not all implementations of job submission protocols have all of the
states of the job model specified here. The job model specified here
is intended to be a superset of most implementations. It is the
purpose of the agent to map the particular implementation's job life
cycle onto the one specified here. The agent MAY omit any states not
implemented. Only the processing and completed states are required to
be implemented by an agent. However, a conforming management
application SHALL be prepared to accept any of the states in the job
life cycle specified here, so that the management application can
interoperate with any conforming agent.
The job states are intended to be user visible. The agent SHALL make
these states visible in the MIB, but only for the subset of job states
that the implementation has. Some implementations MAY need to have
sub-states of these user-visible states. The jmJobStateReasons1 object
and the jobStateReasonsN (N=2..4) attributes can be used to represent
the sub-states of the jobs.
Job states are intended to last a user-visible length of time in most
implementations. However, some jobs may pass through some states in
zero time in some situations and/or in some implementations.
The job model does not specify how accounting and auditing is
implemented, except to assume that accounting and auditing logs are
separate from the job life cycle and last longer than job entries in
the MIB. Jobs in the completed, aborted, or canceled states are not
logs, since jobs in these states are accessible via SNMP protocol
operations and SHALL be removed from the Job Monitoring MIB tables
after a site-settable or implementation-defined period of time. An
accounting application MAY copy accounting information incrementally to
an accounting log as a job processes, or MAY be copied while the job is
in the canceled, aborted, or completed states, depending on
implementation. The same is true for auditing logs.
The jmJobState object specifies the standard job states. The normal
job state transitions are shown in the state transition diagram
presented in Table 1.

INTERNET-DRAFT Job Monitoring MIB, V1.0 February 19, 1999
6 APPENDIX B - Support of Job Submission Protocols
A companion PWG document, entitled "Job Submission Protocol Mapping
Recommendations for the Job Monitoring MIB" [protomap] contains the
recommended usage of each of the objects and attributes in this MIB
with a number of job submission protocols. In particular, which job
submission ID format should be used is indicated for each job
submission protocol.
Some job submission protocols have support for the client to specify a
job submission ID. A second approach is to enhance the document format
to embed the job submission ID in the document data. This second
approach is independent of the job submission protocol. This appendix
lists some examples of these approaches.
Some PJL implementations wrap a banner page as a PJL job around a job
submitted by a client. If this results in multiple job submission IDs,
the agent SHALL create multiple jmJobIDEntry rows in the jmJobIDTable
that each point to the same job entry in the job tables. See the
specification of the jmJobIDEntry.
