Identify Individual CPU Usage

[KPKIND]

Hi *,

I have a system with 2 cpu's in it. If I have to see the cpu usage on my system I run vmstat and get an average usage figure. But If I have to know which CPU (Either CPU1 or CPU2)is sharing what % of the load, How do I know that?

TIA

Hi Mihab,

Thanks for you response. But nmon is not installed on my machine, Is there anyway without using nmon.

TIA

hello,

sar -P ALL 1 100

ps aux|sort -k3rn|pg - top 2 lines are percentage of use on your cpus - then the insuing tells which processes are getting the most cpu.
