Abstract
This memo defines an experimental portion of the Management
Information Base (MIB) for use with network management protocols in
the Internet Community. In particular, it defines objects used for
the management of applications. This MIB complements the System
Application MIB, providing for the management of applications' common
attributes which could not typically be observed without the
cooperation of the software being managed.

Internet Draft Application Management MIB 19 August 1998
1. Introduction
This document furthers the work begun in the systems application mib
[10].
The development of [1], [2], [3], [4], and [8] provides us with a
base of experience in making a variety of applications visible to
management; this specification abstracts out the common aspects of
applications management and provides a generic base usable for the
management of almost any application.
2. Overview
Due to the design decision to not require application
instrumentation, many important topics were not handled in system
application MIB [10]. The following topics are within the scope of
this document:
- Support for generic application throughput
measurements;
- Providing MIB definitions that allow managed entities
to report what they considered to be units of work;
- Providing support for generic application response time
monitoring capabilities;
- Provide explicit support for the management of
applications distributed within a single managed system
("local" distribution);
- Address generic resource management issues, including:
- files in use;
- I/O statistics (from the application's
perspective, not at the operating system or
device driver level);
- application-layer networking resource usage
- Facilities for the control of applications, including:
- Stopping application elements
- Suspending and resuming application elements;
- Requesting reconfiguration (e.g., SIGHUP).
Applmib Working Group Expires February 1999 [Page 3]
Internet Draft Application Management MIB 19 August 1998
Note that these issues are addressed at least in part by other (non-
IETF) standards work, including [11] and [12].
3. Architecture
Object-oriented modeling techniques like subclassing and multiple
inheritance can be emulated in the SNMP information model through the
use of tables with common indexes.
The challenge for the developer of management applications is to
recognize those situations in which various aspects of a single
logical resource are represented in several different tables,
possibly defined in different MIBs.
Most of the management information defined here may pertain to any
number of applications in a managed system. The simplest way of
supporting this requirement within the SNMP information model is to
use tables. This means that the management information for a
particular resource may be found in one or more rows of one or more
tables; the fact that this information pertains to a single resource
may be inferred from the index values used, possibly with the support
of mapping tables. This also means that a single table may contain
management information relevant to a number of applications. This
has significant implementation implications; see the implementation
issues section below for more information.
3.1. Relationships to other MIBs
This section outlines the relationships of the components of this MIB
(usually in the form of common indexing structures) to:
- the systems applications MIB [10]
- the host resources MIB [1]
- the network services monitoring MIB [2]
3.1.1. Relationship to the System Application MIB
The system application MIB defines attributes for management of
applications which can be realized without instrumenting the
application itself. This specification extends that framework to
include additional attributes which will typically require
instrumentation within the managed resource. The sysApplRunElmtIndex
is the key connection between these two MIBs; it is essential that
implementations of this MIB and of the system applications MIB
running concurrently on a given platform employ a consistent policy
for assigning this value to identify running application elements.
Applmib Working Group Expires February 1999 [Page 4]
Internet Draft Application Management MIB 19 August 1998
3.1.2. Relationship to the Host Resources MIB
The Host Resources MIB [1] supplies information on the hardware,
operating system, installed and running software on a host.
The Host Resources MIB has three hardware groups ("hrSystem",
"hrStorage" and "hrDevice") and three software groups ("hrSWRun",
"hrSWRunPerf" and "hrSWInstalled"). Of these, the software groups
are of greatest significance to this MIB.
The software groups define management information on the software
used in the system. The information provided is grouped into (1) the
currently running, (2) the performance and (3) the installed
applications.
The index "hrSWRunIndex" used in the "hrSWRunTable" and other tables
to identify running software by process identifier (or equivalent)
relates information in the Host Resources MIB to information in the
System Applications MIB and this MIB. It is essential that the
values assigned to hrSWRunIndex from the Host Resources MIB be
consistent with the values used for sysApplRunElmtIndex.
3.1.3. Relationship to NSM
The Network Services Monitoring MIB [2] is defined as the base set of
attributes for managing network applications. The Application MIB
includes information normally obtainable only from the managed
resource itself, rather than the supporting system. Due to
differences in index representation, the relationship between the
Network Services Monitoring MIB and the Application MIB is not
formally defined.
4. MIB Structure
This MIB is organized into several groups, which in turn are
organized into tables to provide the monitoring and control of
information relevant to the management of applications. The groups
model:
- the service-level view of applications
- information on open channels (files, connections,
transaction streams) in use by applications
- historical information on former channels
- process-level status and control information
Applmib Working Group Expires February 1999 [Page 5]
Internet Draft Application Management MIB 19 August 1998
These groups are organized into various tables. Information for a
particular running managed application appears in the form of entries
in the appropriate tables. The tables are:
- the tables providing a service-level view, including:
- the service name to service instance table
- the service instance to service name table
- the service instance to running application
element table
- the running application element to service
instance table
- the tables providing information on I/O channels,
including:
- the table of open channels
- the table of open files
- the open connections table
- the transaction statistics tables
- historical information on I/O channels
- the running application element status and control
group
- the running application element status table
- the running application element control table
In order to support SNMPv1, SNMPv2, and SNMPv3 environments, in cases
where counter objects may potentially advance very rapidly, where
sixty-four bit counters have been used thirty-two bit counters
reporting the low-order thirty-two bits of the value have also been
defined.
Since rows in most of these tables will come and go with the running
application elements whose information is contained in them,
sysUpTime.0 is not appropriate as a discontinuity indicator for
counters in these tables. By defining separate discontinuity
indicators for the rows in these tables, entries can come and go as
needed without causing other objects to appear to have
Applmib Working Group Expires February 1999 [Page 6]
Internet Draft Application Management MIB 19 August 1998
discontinuities. As required by [5], the discontinuity indicators
for the various information objects in these tables are identified in
the relevant DESCRIPTION clauses. Note that a discontinuity in one
of these counters does not imply a sysUpTime.0 discontinuity, nor
does a sysUpTime.0 discontinuity imply a discontinuity in any of
these counters.
4.1. The service-level tables
The service-level tables permit the identification of one or more
instances of named services on a system, and the association of
running application elements to these services.
Service names are represented as human-readable strings, using values
assigned by IANA where possible. The allocation of unique values for
service instance identifiers is a local administrative issue; the
values allocated must be constant for the lifetime of the service
instance, and re-use of values should be avoided.
It is important to understand that a service is not the same thing as
a protocol. Rather, some services may be at least partially
described by the protocol(s) used to provide that service.
In deciding what should or should not be considered a service, the
following factors merit consideration:
- is there an identifiable set of resources associated
with providing this service?
- is there a reasonably long-lived server or client
process?
Following this reasoning, one can see where SMTP and HTTP service
providers would be good candidates for classification as services for
purposes of application management, where finger probably would not.
Of course, implementors of this MIB are free to define additional
services. An applicability statement may be an appropriate vehicle
for standardizing how a specific service's information is reported
using this MIB.
4.1.1. The service name to service instance table
The service name to service instance table uses the service name as
its primary key, and the service instance identifier as its secondary
key. It facilitates the identification and lookup of the instances
of a given service in a system.
Applmib Working Group Expires February 1999 [Page 7]
Internet Draft Application Management MIB 19 August 1998
4.1.2. The service instance to service name table
The service instance to service name table uses the service instance
identifier as its primary key, and the service name as its secondary
key. Given a service instance identifier, it facilitates the lookup
of the name of the service being provided.
4.1.3. The service instance to running application element table
The service instance to running application element table uses the
service instance identifier as its primary key, and the running
application element index as its secondary key. This facilitates the
identification of the set of running application elements providing a
given instance of a service.
4.1.4. The running application element to service instance table
The running application element to service instance table uses the
running application element index as its primary key and the service
instance identifier as its secondary key. It identifies the set of
services provided by a given running application element.
4.2. The I/O channel group
Information processed by an application can be modeled using the
concept of a channel. Two kinds of channels, for example, are files
and network connections.
+-------+
| File |
+---------+ /+-------+
+-------------+ | Generic | /
| transaction |----| I/O |-------<
| stream | | Channel | \ +------------+
+-------------+ +---------+ \ | open or |
\| listening |
| connection |
+------------+
For each entry in the open channel table, there will be a
corresponding entry in either the open file table or the open
connection table.
The information flowing on a channel may be structured as
transactions. When the information flow on a channel is being
monitored as a transaction stream, an entry in the transaction stream
table will represent this fact and the associated information about
Applmib Working Group Expires February 1999 [Page 8]
Internet Draft Application Management MIB 19 August 1998
that stream.
To facilitate traversal of these tables and retrieval of information
relevant to a specific running application element or service
instances, the initial indexes of these tables are the same. In each
case, the first index determines whether the second index is
interpreted as a running application element identifier or as a
service instance identifier. The third index serves to uniquely
identify a channel (and consequently, an open connection or file) in
the context of a running application element or service instance.
The transaction stream summary table contains per-stream summaries of
transaction statistics. The transaction flow statistics table
contains statistics broken into both transmit and receive counts for
requests and responses on each stream. The transaction kind
statistics table contains information further broken down by
transaction kind.
The transaction tables have a common structure for their indexing,
with additional indexes added for increasing detail. The initial
three indexes are the same as all the other tables in this group,
serving to uniquely identify each transaction stream.
4.2.1. The open channels table
The following information is available in this table:
- time at which the channel was opened
- number of read requests
- number of bytes read
- time at which most recent read operation was initiated
- number of write requests
- number of bytes written
- time at which most recent write operation was initiated
4.2.2. The open files table
The open files table contains one entry for each file in use by a
manageable running application element. (See [10] for a detailed
definition of a running application element.) The purpose of this
table is to identify the files in use and to record information
peculiar to files not already covered in the open channel table.
Applmib Working Group Expires February 1999 [Page 9]
Internet Draft Application Management MIB 19 August 1998
If multiple running application elements open the same file, there
will be an entry for each running application element opening that
file. Similarly, if a running application element opens a file
multiple times, there will be an entry in this table for the file
corresponding to each open.
The task of combining the information for file activity from this
table (organized by running application element) into per-application
statistics can be accomplished by a manager using the System
Application MIB's [10] sysApplInstallPkgTable to find the installed
application, the sysApplRunTable to find the running instances of
that application, and the sysApplElmtRunTable to find the relevant
values of sysApplElmtRunIndex. The manager, armed with a set of
values for sysApplElmtRunIndex, is now able to retrieve the relevant
portions of the applOpenFileTable and other tables in this MIB.
The following information is available in this table:
- file name
- file size
- current mode (read/write) of this file
By convention, the names "stdin", "stdout" and "stderr" are used when
these streams cannot be resolved to actual file names.
4.2.3. The open connections table
This table provides information on channels that are open connections
or listeners.
The following information is available for each connection:
- identification of the transport protocol in use
- near-end address and port
- far-end address and port
- identification of the application layer protocol in use
4.2.4. The transaction stream summary table
The transaction stream summary table contains per-stream summaries of
transaction statistics. The simple model of a transaction used here
looks like this:
Applmib Working Group Expires February 1999 [Page 10]
Internet Draft Application Management MIB 19 August 1998
invoker | Request | performer
| - - - - - - > |
| |
| Response |
| < - - - - - - |
| |
Since in some protocols it is possible for an entity to take on both
the invoker and performer roles, information here is accumulated for
transmitted and received requests, as well as for transmitted and
received responses. Counts are maintained for both transactions and
bytes transferred. The information represented in this table
includes:
- identification of the underlying connection or file
used for this transaction stream
- a human-readable description of this stream
- a human-readable description of this stream's notion of
what a unit of work is
- the cumulative amount of time spent (as an operation
invoker) waiting for responses (from queueing of
request to arrival of first response)
- the cumulative amount of time spent (as an operation
invoker) receiving responses (time from the arrival of
the first response to the arrival of the last response
in a series of responses to a particular request)
- the cumulative amount of time spent (as an operation
performer) handling requests (time from receipt of
request to queueing of first outgoing response)
- the cumulative amount of time spent (as an operation
performer) sending responses (time from queuing of
first response to the last response in a series of
responses to a particular request)
- the cumulative number of transactions initiated (as an
invoker)
- the cumulative number of transactions processed (as a
performer)
Applmib Working Group Expires February 1999 [Page 11]
Internet Draft Application Management MIB 19 August 1998
4.2.5. The transaction flow statistics table
The transaction flow statistics table contains statistics broken into
both transmit and receive counts for requests and responses on each
stream. In addition to the service instance / running application
element and transaction stream identifier indexes, rows in this table
are indexed by flow direction (transmit or receive) and role
(requests and responses). The information in this table includes:
- the number of transactions processed
- the number of bytes processed
- the time at which the most recent transaction was
processed in this flow
4.2.6. The transaction kind statistics table
The transaction kind statistics table contains summary information
organized by direction, request/response, and transaction kind for
each stream. The indexing of this table is like that of the
transaction flow table, with the addition of a transaction kind
index.
- number of transactions processed
- number of bytes processed
- the time at which the most recent transaction of this
kind in this direction in this stream was processed
4.3. The former channel group
The former channel group has several tables. The former channel
control table controls the retention of history information by a
running application element or service instance. The remaining
tables parallel the structure of the channel group, with one
significant difference in indexing structure. The closed channel
index is independent from the open channel index.
4.3.1. The former channel control table
The former channel control table provides control over the
accumulation of information on former connections for running
application elements and service instances. For each one, this
table, indexed by the running application element or service instance
index, controls whether information on former channels is
accumulated, how many of these history records are retained, how long
Applmib Working Group Expires February 1999 [Page 12]
Internet Draft Application Management MIB 19 August 1998
these are retained (within the lifetime of the process), and a count
of history entries that were deleted before their expiration time in
order to make room for new entries.
4.3.2. The former channel table
The former channel table provides historical information on channels
that have been closed. The number and lifetime of these entries is
controlled, for each running application element or service instance,
by the former channel control table. Most of the information in this
table corresponds to information in the open channel table.
For the connection or file-specific aspects of a given former
channel, an entry will exist in the former connection table or in the
former file table.
4.3.3. The former connection table
For formerly open channels that were connections, connection-specific
historical information is kept in the former connection table. For
each entry in the former connection table, there will be an
identically indexed entry in the former channel table.
4.3.4. The former file table
For formerly open channels that were files, file-specific historical
information is kept in the former file table. For each entry in the
former file table, there will be an identically indexed entry in the
former channel table.
4.3.5. The transaction history tables
Two tables provide per-transaction-kind breakdowns for channels
carrying transaction-structured flows. These tables are analogous to
the transaction flow and kind statistics tables, with similar index
structures.
4.4. The running element status and control group
The running application element status and control group has two
tables.
4.4.1. The running application element status table
This table provides information for a running application element.
Indexed by the sysApplElmtRunIndex, an entry in this table reports
useful information on that running element's resource usage. Entries
in this table contain:
Applmib Working Group Expires February 1999 [Page 13]
Internet Draft Application Management MIB 19 August 1998
- current heap usage for this running application element
- current number of open network connections for this
running application element
- the most recent error status message issued by this
running application element
Note that other information, such as the current number of open files
for this running application element, is available from the
sysapplElmtRunTable in [10].
4.4.2. The running application element control table
This table provides rudimentary control over a running application
element. Indexed by the sysApplElmtRunIndex, an entry in this table
gives a manager with appropriate permissions the ability to suspend
and resume processing by this running element, the ability to request
reconfiguration, and the ability to terminate the running element.
Variables in this table include:
- a suspend/resume control
- a reconfiguration request control
- a termination request control

6. Implementation Issues
Unlike the system application MIB [10], in many environments support
for much of this MIB requires instrumentation built into the managed
resource. Some tables may be implemented by a single monitor
process; for others, the implementation may be distributed within the
managed system with the resources being managed.
As a practical matter, this means that the management infrastructure
of the managed system must support different subagents taking
responsibility for different rows of a single table. This can be
supported by AgentX [13], as well as some other subagent protocols
such as [14], [15], and [16].
The sysApplRunElmtIndex is the key connection between this MIB and
the systems application MIB. Implementations of these two MIBs
intended to run concurrently on a given platform must employ a
consistent policy for assigning this value to running application
elements.
Some of the objects defined in this MIB may carry a high run-time
cost in some environments. For example, tracking transaction elapsed
time could be expensive if it required two kernel calls (start and
finish) per transaction. Similarly, maintaining tables of per-
transaction information, rather than aggregating information by
transaction type or transaction stream, could have significant
storage and performance impacts.
Unless a collision-free mechanism for allocating service instance
indexes is in place, the structure of the service-level tables makes
an index-reservation mechanism necessary. AgentX [13] is an example
of a subagent protocol capable of satisfying this requirement.
7. Intellectual Property
The IETF takes no position regarding the validity or scope of any
intellectual property or other rights that might be claimed to
pertain to the implementation or use of the technology described in
this document or the extent to which any license under such rights
might or might not be available; neither does it represent that it
has made any effort to identify any such rights. Information on the
IETF's procedures with respect to rights in standards-track and
standards-related documentation can be found in BCP-11. Copies of
claims of rights made available for publication and any assurances of
licenses to be made available, or the result of an attempt made to
obtain a general license or permission for the use of such
proprietary rights by implementors or users of this specification can
be obtained from the IETF Secretariat.

9. Security Considerations
By making potentially sensitive information externally accessible,
the capabilities supported by the MIB have the potential of becoming
security problems.
The tables in this MIB are organized to separate sensitive control
capabilities from less sensitive usage information. For example, the
objects to control application suspend/resume are separated from
those to handle reconfiguration, which in turn are distinct from
those for termination. This recognizes the need to support
configurations where the level of authorization needed by a manager
to do a "reconfigure" might be substantially less than the level
needed to terminate an application element. By keeping these in
separate columns, we make it possible to set up access control that
allows, for example, "reconfigure" but not "kill".
The MIB is structured to be useful for managers with read-only access
rights.
The capabilities supported by this MIB include several that may be of
value to a security administrator. These include the ability to
monitor the level of usage of a given application, and to check the
integrity of application components.
