NAME

mpstat- report per-processor statistics

SYNOPSIS

/usr/bin/mpstat [-p| -P set] [interval [ count]]

DESCRIPTION

mpstat reports per-processor statistics in tabular form. Each row of the table represents the activity of one processor. The first table summarizes all activity since boot; each subsequent table summarizes activity for the preceding interval. All values are rates (events per second) unless otherwise noted.

During execution of this kernel status command, the "state" of the kernel can change. An example would be CPUs going online or offline. mpstat reports this as State change.

mpstat reports the following information:

CPU

processor ID

minf

minor faults

mjf

major faults

xcal

inter-processor cross-calls

intr

interrupts

ithr

interrupts as threads (not counting clock interrupt)

csw

context switches

icsw

involuntary context switches

migr

thread migrations (to another processor)

smtx

spins on mutexes (lock not acquired on first try)

srw

spins on readers/writer locks (lock not acquired on first try)

syscl

system calls

usr

percent user time

sys

percent system time

wt

percent wait time

idl

percent idle time

For the -p option, mpstat also reports the following information:

set

processor set membership of the CPU

OPTIONS

The following options are supported:

-p

Report processor set membership of each CPU. Sort the output by set. The default output is sorted by CPU number.

-P set

Display only those processors in the specified set.

interval

Report once each interval seconds.
