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 RFC1442 [1] defines the StrUCture of Management Information

(SMI), the mechanisms used for describing and naming objects

for the purpose of management.

o STD 17, RFC1213 [2] defines MIB-II, the core set of managed

objects (MO) for the Internet suite of protocols.

o RFC1445 [3] defines the administrative and other

architectural ASPects of the management framework.

o RFC1448 [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

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.

- The dsaOpsTable provides summary statistics on the accesses,

operations and errors.

- The dsaEntriesTable provides summary statistics on the entries

held by the DSA and on cache performance.

- 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.
