MPSTAT(1) General Commands Manual MPSTAT(1)
mpstat - show multi-processor usage
/usr/kvm/mpstat [ interval [ count ] ]
This program is only available on sun4m architectures.
mpstat enters the system and shows average and per-processor percentage
usage data during a particular time interval. The first group of data
represents the average of all the processors in the system while the
second and subsequent data groups represent particular processors, with
their particular name designations above each group.
Without an interval or count option, vmstat displays a one-line summary
of MP system activity since the system has been booted. If interval is
specified, vmstat summarizes activity over the last interval seconds.
If a count is given, the statistics are repeated count times.
The particular fields of each data group give a breakdown of percentage
usage of CPU time:
us user time for normal processes
ni time for processes with an altered scheduling priority (nice(1))
sy system time
id CPU idle
