Use the top command.

Can also use the sar command

sar -u 1 10
Check the CPU every second for 10 seconds.

sar -u 5 100
Check the CPU every 5 seconds for 100 seconds

The -u switch to sar is for the CPU

Use "sar" (sar 5 10) as it is universal.

"vmstat" (vmstat 5 10) as it is also universal.

You may also use "top".

If you're running Enterprise OE (ie on an rp8400 or SuperDome).. you have Glanceplus (gpm or "glance -g") or you can use MeasureWare.
