For our WebSphere® Application Server performance tests we used SAR to collect performance statistics data.

SAR

The SAR program collects reports and saves system activity information. The contents of selected cumulative activity counters in the operating system are written to standard output. The accounting system then uses supplied SAR parameters and writes information based on the given parameters.

  9. Start the SAR data collection
  10. Start the monitor data collection
  11. Run the workload for approximately seven minutes
  12. Stop the workload
