Processor Utilization - NEC Express5800 Maintenance Manual

Chapter 3 Appendix

3.2.3 Processor utilization

The utilization rate of all logical processors is given by executing the mpstat command provided in a Linux
distribution.
For Red Hat Enterprise Linux 5, sysstat-[version].rpm contains the command.
Execution example
# mpstat -P ALL
Execution result
Linux 2.6.18-164.el5 (localhost.localdomain) 11/17/09
17:59:30 CPU %user
17:59:30 all 1.23
17:59:30 0 0.42
17:59:30 1 0.41
17:59:30 2 2.17
17:59:30 3 1.85
17:59:30 4 0.87
17:59:30 5 2.42
17:59:30 6 0.30
17:59:30 7 1.36
You can acquire the processor utilization rate by subtracting %idle from 100%.
