System and method for obtaining network performance data
First Claim
1. A method for obtaining performance measurements for at least one selected resource in a computer network, said computer network containing a plurality of resources and executing a communication access program to control communication sessions between pairs of said plurality of resources, comprising the steps of:
- activating a performance exit interface in the communication access program to signal that performance data is to be collected for said at least one selected resource;
requesting said communication access program to start the collection of performance data for each communication session between said pairs of plurality of resources having said at least one selected resource as one of said pairs of plurality of resources;
collecting said performance data for said each communication session having said at least one selected resource as one of said pairs of plurality of resources without impairing any trace facilities of said communication access program and providing said performance data to said performance exit interface;
processing said performance data to determine performance measurements for said at least one selected resource; and
terminating said collection of performance data for said each communication session and deactivating said performance exit interface.

Abstract
A system and method are provided for monitoring network performance in a network controlled by a communication access method. The communication access method is modified to communicate with a network performance monitor so that the communication access method will monitor its internal processing for information units for a predetermined resource upon request of the network performance monitor. The communication access method time stamps each inbound and outbound information unit for the predetermined resource and sends formatted data regarding each information unit, including the time stamp data, to a predetermined exit from the communication access method. The network performance monitor obtains the formatted data from the performance exit and processes the formatted data to determine network performance in relation to the predetermined resource.

5. A system for obtaining performance measurements for at least one selected resource in a computer network, said computer network containing a plurality of resources and executing a communication access program to control communication sessions between pairs of said plurality of resources, comprising:
-
means for activating a performance exit interface in the communication access program to signal that performance data is to be collected for said at least one selected resource; means, cooperative with said means for activating, for requesting said communication, access program to start the collection of performance data for each communication session between said pairs of plurality of resources having said at least one selected resource as one of said pairs of plurality of resources; means, responsive to said means for requesting, for collecting said performance data for said each communication session having said at least one selected resource as one of said pairs of plurality of resources without impairing any trace facilities of said communication access program; means, cooperative with said means for collecting, for providing said performance data to said performance exit interface; means for processing said performance data that has been provided to said performance exit interface; means cooperative with said means for processing, for terminating said collection of performance data for said each communication session; and means, cooperative with said means for terminating, for deactivating said performance exit interface. - View Dependent Claims (6, 7, 8)
