MPSTAT(1)                   General Commands Manual                  MPSTAT(1)



NAME
       mpstat - show multi-processor usage

SYNOPSIS
       /usr/kvm/mpstat [ interval [ count ] ]

AVAILABILITY
       This program is only available on sun4m architectures.

DESCRIPTION
       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
