Understanding resource monitoring statistics

When resource monitoring is active, CICSPlex® SM collects data about the specified resources as frequently as indicated by the sample interval.

This data reflects:
  • The type of information available via the CICS COLLECT STATISTICS command.
  • CICSPlex SM derived values. A derived value is a rate, average, or percentage that results from CICSPlex SM processing of CICS statistics.
All of the data collected about the monitored resources is available by using the monitoring views. Monitor views are described in CICSPlex System Manager Monitor Views Reference.

Important

In order for CICSPlex SM to gather certain task-related data shown in the WUI transaction monitoring views (LOCTRAN objects) and task monitoring views (TASK objects), the CICS monitoring facility (CMF) must be active and you must be collecting performance class data. For an active system, you can open the CICS system definition view and change the Monitoring status field to ON. This has the same effect as issuing the following EXEC CICS commands:
  • EXEC CICS SET MONITOR STATUS(ON)
  • EXEC CICS SET MONITOR PERFCLASS(PERF)
However, these changes remain in effect only while the CICS® system is active. To permanently activate CICS performance class data monitoring, use the CICS system initialization parameters MN=ON and MNPER=ON . You can choose to collect this data for use by CICSPlex SM, but not have it written to an SMF data set. For information on suppressing CMF records, see the discussion of system parameters in Using the CICS Monitoring Facility (CMF) with CICSPlex SM .
