z/VM MONWRITE - Collect CP *MONITOR data

Edit online
If your Linux™ system runs as a guest operating system under z/VM® and encounters performance problems, use the MONWRITE utility and include CP *MONITOR data in the problem report.
The z/VM monitor records are in binary format. Make sure that:
  • The records are packed and tersed correctly.
  • The record size settings are correct.
  • The binary to ASCII conversion is made correctly.

For more information about how to collect and upload z/VM MONWRITE data, see www.ibm.com/vm/perf/tips/collect.html

Usage notes

  • The sadc and sar files must cover the same time interval as the z/VM MONWRITE data.
  • Use the default sampling time interval of 1 minute.
