This Recommendation | International Standard defines a systems management function which may be used by an

application process in a centralized or decentralized environment to interact for the purposes of systems-management, as

defined by CCITT Rec. X.700 | ISO/IEC 7498-4. This Recommendation | International Standard defines the response

time monitoring function that consists of services, functional units, generic definitions and protocols. It is positioned in

the application layer of ITU-T Rec. X.200 | ISO/IEC 7498 and is defined according to the model provided by

ISO/IEC 9545. The role of systems management functions are described by ITU-T Rec. X.701 | ISO/IEC 10040.

This Recommendation | International Standard:

? establishes user requirements for the response time monitoring function;

? establishes a model that relates the services and generic definitions provided by this function to user

requirements;

? defines the services provided by the function;

? defines generic notification type; and

? specifies the protocol that is necessary in order to provide the services.

This Recommendation | International Standard does not:

? define the nature of any implementation intended to provide the response time monitoring function;

? specify the manner in which management is accomplished by the use of the response time monitoring;

? define the nature of any interactions which result in the use of the response time monitoring;

? specify the services necessary for the establishment, normal and abnormal release of a management

association;

? preclude the definition of further notification types.

The functions and the management information defined in this Recommendation | International Standard include:

? Summarization of the response time on any request of information and its management;

? Definition of the relationship on response monitoring;

? Setting and modification of the monitoring and the summarization conditions;

? Scheduling of the monitoring and the summarization; and

? Notification when response information or its statistical result is over a threshold.

The functions and the management information defined in this Recommendation | International Standard do not include:

? Management information definitions for summarization of response time statistical;

? How to retrieve response times locally (e.g., the test function to confirm response times); and

? Local mechanisms to summarize information related to the response request and response.
