Using RMF to monitor Spark workload
The z/OS® Resource Measurement Facility (RMF) is a tool for z/OS performance measurement and management. RMF collects performance data for z/OS and Parallel Sysplex® environments and generates reports that allow you to monitor and tune your systems according to your business needs.
- 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 background sessions with a variety of options that determine the type of data to collect and where to store it. For more information about setting up the RMF monitors, see z/OS RMF User's Guide.
All three RMF monitors create reports, as does the Postprocessor. The following topics provide an overview of the reports that are most relevant to monitoring a Spark workload. For complete information about RMF reports, see z/OS RMF Report Analysis.
