X.500 Directory Monitoring MIB
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
This document defines a portion of the Management Information Base
(MIB). It defines the MIB for monitoring Directory System Agents
(DSA), a component of the OSI Directory. This MIB will be used in
conjunction with the APPLICATION-MIB for monitoring DSAs.

1. The SNMPv2 Network Management Framework
The major components of the SNMPv2 Network Management framework are
described in the documents listed below.
o RFC 1442 [1] defines the Structure of Management Information
(SMI), the mechanisms used for describing and naming objects
for the purpose of management.
o STD 17, RFC 1213 [2] defines MIB-II, the core set of managed
objects (MO) for the Internet suite of protocols.

RFC 1567 X.500 Directory Monitoring MIB January 1994
o RFC 1445 [3] defines the administrative and other
architectural aspects of the management framework.
o RFC 1448 [4] defines the protocol used for network access to
managed objects.
The framework is adaptable/extensible by defining new MIBs to suit
the requirements of specific applications/protocols/situations.
Managed objects are accessed via a virtual information store, the
MIB. Objects in the MIB are defined using the subset of Abstract
Syntax Notation One (ASN.1) defined in the SMI. In particular, each
object type is named by an OBJECT IDENTIFIER, which is an
administratively assigned name. The object type together with an
object instance serves to uniquely identify a specific instantiation
of the object. For human convenience, often a textual string, termed
the descriptor, is used to refer to the object type.
2. MIB Model for DSA Management
A DSA-manager may wish to monitor several aspects of the operational
DSA. He/she may want to know the process related aspects-the
resource utilization of the operational DSA; the network service
related aspects e.g., inbound-associations, outbound-associations,
operational status, and finally the information specific to the DSA
application - its operations and performance.
The MIB defined in this document covers the portion which is specific
to the DSA-application. The network service related part of the MIB,
and the host-resources related part of the MIB, as well other parts
of interest to a Manager monitoring the DSA-application, are covered
in separate documents [6] [7].
3. The DSA functions and operations
The Directory System Agent [DSA], a component of the OSI-Directory
[5] [9], is an application process. It provides access to the
Directory Information Base [DIB] to Directory User Agents [DUA]
and/or other DSAs. Functionally , a User [DUA] and the Directory are
bound together for a period of time at an access point to the
Directory [DSA]. A DSA may use information stored in its local
database or interact with (chain the request to) other DSAs to
service requirements. Alternatively, a DSA may return a reference to
another DSA.
The local database of a DSA consists of the part of the DIT that is
mastered by the DSA, the part of the DIT for which it keeps slave
copies and cached information that is gathered during the operation
