The CPCLPAR screen of SYSVIEW gives a real view of the system's behavior but it is updated every 5 minutes and there are 48 lines only.
SYSVIEW 17.0 - z/OS supported release -
The time interval and the number of lines are not configurable. This data is collected by IBM, and there are 48 5-minutes buckets for the 4H rolling average. This isn't data that SYSVIEW is collecting, calculating, or storing. It's all from IBM.
About the CPCLPAR history, it's not configurable too. One option is that with the Event Capture option, a capture can be scheduled for that display, maybe every four hours.
