Overriding resource monitoring attributes

The monitor specifications associated with a CICS® system determines whether resource monitoring is to be active when the CICS system starts, how long collected data is to be retained after monitoring stops, and the sample interval to be used for one or more resource types.

You can override any of the attributes defined in a monitor specification by changing the definition of the CICS system that is to use that specification. This might occur when, for example, multiple CICS systems are using the same monitor specification and you want the data retention period to be different for one of those systems. To override the monitor specification for a specific CICS system, you can use the views:
CICS system definitions (CSYSDEF object)
To permanently override part or all of a monitor specification. Values changed using this view are stored in the data repository and used every time the CICS system starts. For additional information about using the CICS system definitions view, see Working with CICS system definitions.
MASs known to CICSplex (MAS object)
To temporarily override all or part of the monitor specification currently being used by an active CICS system. Values affected by this view remain in effect as long as the CICS system is running or until you change them. For additional information about the MASs known to CICSplex views, seeWorking with MAS topology definitions.
