Figure 1. Collecting historical data in RMF PM

Collecting historical data in RMF PM. This dialog is accessible from the product and includes accessible help information.

You can specify a start date/time and a stop date/time. After you've pressed the Ok button, all available performance samples for all DataViews of this PerfDesks for the specified time range are automatically collected.

Note that RMF PM gets its data from the z/OS host, meaning that all performance data has to be calculated by the z/OS RMF™ Monitor III. So if you're calculating the data for many different times, you can use some amount of CPU on the host.
