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.

Mansfield & Kille [Page 1] 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

Mansfield & Kille [Page 2] RFC 1567 X.500 Directory Monitoring MIB January 1994

 of the DSA.
 The specific operations carried out by the DSA are: Read, Compare,
 AddEntry, ModifyEntry, ModifyRDN, RemoveEntry, List, Search. There is
 also the special operation Abandon.  In response to requests results
 and/or errors are returned by the DSA.

4. MIB design

 The basic principle has been to keep the MIB as simple as possible.
 The Managed objects included in the MIB are divided into three tables
 - dsaOpsTable, dsaEntryTable and dsaIntTable.
  1. The dsaOpsTable provides summary statistics on the accesses,

operations and errors.

  1. The dsaEntriesTable provides summary statistics on the entries

held by the DSA and on cache performance.

  1. The dsaIntTable provides some useful information on the

interaction of the monitored DSA with peer DSAs.

 There are references to the Directory itself for static information
 pertaining to the DSA. These references are in the form of "Directory
 Distinguished Name" [8] of the corresponding object.  It is intended
 that DSA management applications will use these references to obtain
 further related information on the objects of interest.
