The CICS monitoring facility

CICS monitoring collects data about the performance of all user- and CICS-supplied transactions during online processing for later offline analysis. The records produced by CICS® monitoring are of the MVS™ System Management Facility (SMF) type 110, and are written to an SMF data set.

Note:
Statistics records and some journaling records are also written to the SMF data set as type 110 records. You might find it particularly useful to process the statistics records and the monitoring records together, because statistics provide resource and system information that is complementary to the transaction data produced by CICS monitoring. The contents of the statistics fields are described in Appendix A. CICS statistics tables. The procedure for processing them using the statistics utility program, DFHSTUP, is in the CICS Operations and Utilities Guide.

Monitoring data is useful both for performance tuning and for charging your users for the resources they use.

For information on the performance implications of using the CICS monitoring facility, see CICS monitoring facility: performance considerations.
