When resource monitoring is active, CICSPlex® SM collects data about the specified resources as frequently as indicated by the sample interval. This data reflects:
All of the data collected about the monitored resources
is available via the monitoring views (EUI monitor views are described in CICSPlex SM Monitor Views Reference).
In order for CICSPlex SM to gather certain task-related data shown
in WUI transaction monitoring views and the EUI views MLOCTRAD, MLOCTRA2,
MREMTRAD, and TASKD, 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 (WUI) view or CICSRGN2
(EUI) view and overtype these fields with the specified values:
This has the same effect as issuing the following EXEC CICS commands:
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 CICS Transaction Server for z/OS® Installation Guide.
When resource monitoring of a particular resource type is active, data is collected and accumulated until:
With CICS, you can collect data about the performance of all user- and CICS-supplied transactions. These records are written to an MVS™ System Management Facility (SMF) data set as type 110 records. These records can then be used for offline analysis. (If statistics records are also to be written to the SMF data set, you can process the statistics and monitoring records together to obtain resource and system information that complements the transaction data produced by CICS monitoring.)
With CICSPlex SM, you can collect data about all resource types. That is, you can obtain information about one or more:
You can also get information about CICS systems, dynamic storage areas (DSAs), transaction classes, local shared resource (LSR), and temporary storage.
