Gathering data

RMF™ gathers data using three monitors:
  • short-term data collection with Monitor III
  • snapshot monitoring with Monitor II
  • long-term data gathering with Monitor I and Monitor III

The system operator starts all monitors as non-interactive (background) sessions with a variety of options that determine what type of data is collected and where it is stored. The data gathering functions run independently on each system, but each monitor can be started sysplex-wide by one operator command.

You can run data gathering on each z/OS® system and use the RMF Sysplex Data Server to have all data available on the one system on which you run your performance management tasks.
