This part of ISO/IEC ISP 12060 specifies the General log control profile, AOM231, which is applicable to end systems operating in the Open Systems Interconnection (OSI) environment. AOM231 specifies a combination of OSI standards which collectively provide General log control. General log control provides a means for selecting which notifications (generated by managed objects) or incoming event reports are logged within the open system; the criteria for selection are specified in a Log managed object.
AOM231 also provides a means for initiating, terminating, suspending and resuming the logging process as well as modification of the logging selection criteria and retrieving information from the logs. These capabilities are achieved by a set of operations upon, and a set of notifications generated by, the log object.
AOM231 also specifies use of a combination of standards that collectively provide the subset of the Common Management Information Service required by this part of ISO/IEC ISP 12060.
The support of the complete set of operation and notification services and of the management attributes does not imply that all these features shall be used in all instances of communication. The selection of the features depends on the requirements of the MIS users.
The definitions and conventions used in this part of ISO/IEC ISP 12060 are specified in ISO/IEC ISP 12059-0, Common definitions for management function profiles.
AOM231 is applicable in an environment in which end systems are able to take a manager role, an agent role or both. A system acting in the role of a manager is capable of requesting the specified set of operations upon a Log support managed object which is in the system acting in the role of an agent; the notifications that are logged are also in the system acting in the role of an agent.
Figure 1 illustrates only one of those configurations, one in which one system is acting in a manager role and a further system is acting in the agent role.
The roles of manager and agent may be determined in advance, for the duration of an association or the duration of a single management interaction. The application context is defined in Systems Management Overview (ISO/IEC 10040).
NOTE - Negotiation of functional units is optional.
AOM231 references the following standards:
(Application Layer): ISO/IEC 10164-6, Log control function; ISO/IEC 10164-1, Object management function; ISO/IEC 10164-2, State management function; ISO/IEC 10164-4, Alarm reporting function; ISO/IEC 10165-2, Definition of management information; ISO/IEC 9595, 9596-1, CMIS and CMIP; ISO/IEC 9072-1, 2, ROSE; ISO/IEC 11183-2, CMISE/ROSE for AOM12 - Enhanced management communications; ISO 8649, 8650, ACSE; ISO/IEC ISP 11183-1, Specification of ACSE, Presentation and Session.
(Presentation Layer): ISO 8822, 8823, Presentation; ISO/IEC 8824, 8825, ASN.1; ISO/IEC ISP 11183-1, Specification of ACSE, Presentation and Session.
(Session Layer): ISO 8822, 8823, Session; ISO/IEC 8326/Add.2; ISO/IEC 8327/Add.2; ISO/IEC ISP 11183-1, Specification of ACSE, Presentation and Session.
AOM231 includes by reference the subset of the Enhanced Management Communications profile (AOM12) that is requried to support the above services.
NOTE - Refer to the description of AOM12 for further information about the communications support including specification of the protocol stack.
Claims of conformance to both objects and AOM231 require that all notifications of all objects can be discriminated.
An implementation conforming to AOM231 in the agent role shall support a mechanism to ensure that the notifications emitted by the log can be sent to a managing system.
An end system implementing AOM231 can interwork with an end system implementing the same profile in a complementary role. A system implementing the Enhanced Management Communications profile (AOM12) will be compatible with the communications aspects of AOM231.
1.3 Position within the Taxonomy
AOM231 is identified in ISO/IEC TR 10000-2 as:
AOMnn - OSI Management;
AOM2 - Management Functions;
AOM23 - Log Control;
AOM231 - General Log Control.
AOM231 may be combined with any T-Profile (identified in ISO/IEC TR 10000-2) specifying the OSI connection-mode transport service.
