Systems Management: Reference Model
Systems Management: Reference Model
Copyright © 1997 The Open Group
X/Open Systems Management Programme
The X/Open Systems Management Programme is defined in terms of a
suite of documents that, taken together, will describe all the
components needed to achieve the goals
stated in
Goals and Objectives
.
The first of these documents is the X/Open Systems Management Problem
Statement (see reference PS).
The Problem Statement, published in 1991 as a Snapshot,
provides an overview of the problem,
and also includes a review of activities current at that time.
The Reference Model builds on the Problem Statement, providing a
framework in which the various components of the solution
can be identified.
The individual components will be defined in subsequent documents.
The current X/Open work program is developing a coherent family of documents that
address the various components needed in order to provide an open, portable,
interoperable management system. The documents can be divided
into a number of groups according to their functionality. These
groups are described below.
In the following sections, documents already completed are
indicated by an asterisk (*). The descriptions given below are
intended for overall guidance only. For more specific
information regarding planned time-scales, refer to the
Distributed Systems Management section of the X/Open Technical
Programme (see reference XTP).
Strategic Documents
The first group of documents
provides the framework and strategy that defines the overall
approach, and consists of the following documents:
-
Systems Management Problem Statement (*): Provides an overview of the
problem space and a review of activities in the area of system management.
-
Systems Management Reference Model (*): This document.
-
Guide to Systems Management: It is envisaged that a tutorial-style document
will ultimately be provided which will describe the use of the distributed
systems management specifications developed under the systems management
work program.
Managed Object Definitions
The second group is concerned with the definition of Managed Objects.
It consists
of the following:
-
Managed Object Guide (XMOG) (*): Provides a guide to the principles,
techniques and processes used in defining Managed Objects.
-
Guide to Translating GDMO to XOM (*): Provides a set of rules for translating
object definitions based on the ISO Guidelines for the Definition of Managed
Objects into the XOM form required by XMP.
-
Guide to Translating GDMO to IDL: This document will provide guidance for
translating Managed Object definitions defined using ISO GDMO into IDL
definitions required for use with OMG CORBA-based technology.
-
DMI Contents Package(*): This document provides the necessary definitions of
management support objects, based on the OSI Definition of Mangement
Information, for use with the XMP API.
-
Managed Object Definitions: There will be series of documents that provide
the object definitions corresponding to the Resources that need to be managed.
In most cases this will be achieved by reference to existing definitions.
Management API Specifications
The third group will address APIs to Management Services, including
communications services:
-
Identification of Management Services (XIMS) (*): Identifies the various services
required for implementation of distributed management systems.
-
Management Protocols API (XMP) (*): Defines programming interfaces to
management communications services provided by CMIP and SNMP.
-
Common Object Request Broker Architecture (CORBA) (*): This document,
developed by the Object Management Group and published as an X/Open
specification, is not formally a part of the systems management program.
However, it forms an integral part of the systems management APIs and is a
key technology in the realisation of many distributed systems management
systems.
-
Management Services APIs: Interfaces will be defined to provide access to the
underlying Management Services provided by the framework.
Interworking Specifications
The fourth group addresses interoperability issues, namely the protocol profiles
necessary to achieve interworking between different implementations of conformant
systems.
-
Management Protocol Profiles (XMPP) (*): Describes the protocol options to be
used in an X/Open System Management implementation. This document makes
reference to the International Standardised Profiles (ISPs) relevant to CMIP, and
the appropriate RFCs for SNMP.
-
ISO/CCITT and Internet Management: Coexistence and Interworking
Strategy (*):
This document addresses the issues arising from the need to accommodate both
OSI and Internet management protocols within a common environment.
Management Application Specifications
The fifth group of specifications will address specific functional areas corresponding
to real end-user requirements, and will provide the definitions necessary to provide
portability and interoperability in the development of solutions to those
requirements. Functional areas expected to be covered include the following:
-
Networked Backup and Restore: This specification will provide the necessary
object definitions and interfaces to provide networked backup and restore
capability. It will provide a framework for extending backup and restore
beyond file systems, allowing other sub-systems to be backed up, and promoting
a plug'n'play approach to the provision of the various components of a
backup and restore system.
-
Performance Management: Performance management specifications will
provide the low-level data gathering functionality that is needed to allow
portable high-level interpretation tools to be developed.
-
Accounting Management: As with performance management, it is anticipated
that work in this area will be concerned with the low-level data gathering
functionality, thus providing access to the information needed by Resource
accounting packages for billing and other purposes.
-
Software Management: It is is anticipated that work in this area will be based
on the work currently being undertaken within the POSIX 1003.7 System
Administration working group.
-
Printer Management: It is is anticipated that work in this area will be based on
the work currently being undertaken within the POSIX 1003.7 System
Administration working group.
