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.
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)
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 .
