System Management Functions

There are a number of general functions not related to a particular TMN functional area or hierarchical layer, but basically applicable to all of them.  These functions are labelled Information technology (IT) — Open Systems Interconnection (OSI) — Systems Management functions (SMF), hence called SMFs or SMURFs, listed in M.3400, and defined individually in the X.7xx series (identical to ISO/IEC 10164-xx series).

• Object management function
  [X.730]  basically defines the handling of the (manager/agent) 'management operations' at 'Pass Through' level:  PT_CREATE, PT_DELETE, PT_SET, PT_GET, PT_CANCEL_GET, PT_ACTION and PT_EVENT_REPORT.
  Not very interesting.
• State Management function
  [X.731]  The management state of a managed object represents the instantaneous condition of availability and operability of the associated resource from the point of view of management.  The purpose of the management state is to control the general availability of a resource and to make visible information about that general availability.
  A very useful recommendation.
• Attributes for representing Relationships
  [X.732]
• Alarm Reporting function
  [X.733] Mainly about the (alarm) message itself, but has some very useful parts.
• Event Report management function
  [X.734] Forwarding of selected Event Reports
• Log Control function
  [X.735]
• Security Alarm Reporting function
  [X.736]
• Confidence and Diagnostic Test categories
  [X.737]
• Summarization function
  [X.738]  specifies methods to observe and report on attribute values for performance related purposes.  Attributes may be of the same or different types.  Results of observations may be provided through notifications as they are collected or 'buffered' and provided en-bloc.
• Metric Objects and Attributes
  [X.739]  specifies performance tools to observe characteristics of resources either directly within managed objects or through the use of metric objects.  The tools also include provision of statistics, such as mean and percentile calculations, and thresholds to generate notifications.
• Security Audit Trail function
  [X.740]
• Objects and Attributes for Access Control
  [X.741]
• Usage Metering function for accounting purposes
  [X.742]  specifies models, protocols and managed objects for accounting meter function.
• Software Management function
  [X.744]
• Test Management function
  [X.745]  specifies a model and managed objects for the invocation of tests on remote resources.  Tests may be controlled and subject to monitoring, suspension and resumption during application or uncontrolled and where results are returned until complete.
• Scheduling function
  [X.746]  specifies a model and management information for the creation and administration by a remote manager of activity schedules for management activity;  this includes such things as schedules for performance data collection and scheduled, or routine test.  This Specification is of generic application and can be used by many different types of application.  It is expected to be adopted for TMN use.  {It includes Management Conformance Statements (MCS).}
• Management Domain and Management Policy management function
  [X.749]
• Management Knowledge management function
  [X.750]
• Changeover function
  [X.751]
• Command Sequencer for Systems Management
  [X.753]
• Trouble Management function
  [X.790]  specifies the handling of 'trouble' in a network with respect to the customer/­provider interworking.
• Profile for trouble management function for ITU-T applications
  [X.791]
