CPU Load in Solaris

[htmlmasterdave]

This is a really quick question, but for an assignment, I need to know how to be able to print out the cpu usage for the last 1, 5 and 15 minutes, but it must be in integers. Does anyone know? The help is greatly appreciated 🙂

You sure it's cpu usage and not load? Because the "uptime" command shows load over those exact (I believe, anyways) timeframes.

Use sar.

NAME
sar - system activity reporter

SYNOPSIS
sar [ -aAbcdgkmpqruvwy ] [ -o filename ] t [ n ]

sar [ -aAbcdgkmpqruvwy ] [ -e time ] [ -f filename ] [
-i sec ] [ -s time ]

DESCRIPTION
In the first instance, sar samples cumulative activity
counters in the operating system at n intervals of t
seconds, where t should be 5 or greater. If t is specified
with more than one option, all headers are printed together
and the output may be difficult to read. (If the sampling
interval is less than 5, the activity of sar itself may
affect the sample.) If the -o option is specified, it saves
the samples in filename in binary format. The default value
of n is 1.

You could put a script into the cron to call sar if you have irregluar time intervals.
