The System Command
Display System Statistics
To display system statistics for CPUs, disks, Ethernet ports, and NFS, use the
system show
stats
operation. The time period covered is from the last reboot, except with
interval
and
count
.
An
interval
, in seconds, runs the command every number of seconds (
nsecs
) for the number
of times in
count
. The first report covers the time period since the last reboot. Each subsequent
report is for activity in the last
interval
. The default interval is five seconds.
The
interval
and
count
labels are optional when giving both an interval and a count. To give
only an interval, you can enter a number for
nsecs
without the
interval
label. To give only a
count, you must enter the
count
label and a number for
count
.
The
start
and
stop
options return averages per second of statistics over the time between the
commands.
system show stats [start | stop | ([interval nsecs ] [count
count ])]
The display is similar to the following:
# system show stats

idle time. The
Filesystem line displays the time that has passed since the file system was last
started.
