.SH DESCRIPTION
|
|
.IX "mpstat command" "" "\fLmpstat\fP \(em show multi-processor usage"
|
|
.B 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.

|
.LP
|
|
Without an
|
|
.I interval
|
|
or
|
|
.I count
|
|
option,
|
|
.B vmstat
|
|
displays a one-line summary of MP system activity
|
|
since the system has been booted. If
|
|
.I interval
|
|
is specified,
|
|
.B vmstat
|
|
summarizes activity over the last
|
|
.I interval
|
|
seconds. If a
|
|
.I count
|
|
is given, the statistics are repeated
|
|
.I count
|
|
times.
|
|
.LP
|
|
The particular fields of each data group give a breakdown of
|
|
percentage usage of CPU time:

|
.B us

user time for normal processes
|

.TP
|
|
.B ni
|
|
time for processes with an altered scheduling priority (\fInice(1)\fR)
