This section explains how to use the Resource Measurement Facility (RMF™) to obtain transaction response time reporting.
CICS® monitoring facility with RMF provides a very useful tool for performing day-to-day monitoring of CICS transaction rates and response times.
The objective of using the CICS monitoring facility with RMF is to enable transaction rates and internal response times to be monitored without incurring the overhead of running the full CICS monitoring facility and associated reporting. This approach may be useful when only transaction statistics are required, rather than the very detailed information that CICS monitoring facility produces. An example of this is the monitoring of a production system where the minimum overhead is required.
The CICS monitoring facility issues an MVS™ workload manager IWMRPT or IWMMNTFY macro that gives the following SYSEVENT information to the MVS workload manager (WLM):
This member defines the options that are used on the RMF Monitor I background session. This session does not include transaction reporting as used by CICS, but a Monitor I session has first to be active. A WKLD has to be defined to allow TRX reporting to be activated.
This member defines the options that are used on the RMF Monitor II background session. This session performs transaction reporting as used by CICS. TRX defaults to TRX(ALLPGN) which reports on all transactions. Individual transactions can be named if desired.
A RMF job has to be started and this includes the Monitor I session. The RMF job should be started before initializing CICS. The RMF Monitor II session is started by the command F RMF,S aa,MEMBER(xx) where ‘aa’ indicates alphabetic characters and ‘xx’ indicates alphanumeric characters.
