View CPU usage of individual processors in UNIX

I am trying to diagnose a problem on a server box that I believe is related to CPU usage.

However, when I log in to the box and run 'top' I see a %CPU of 160 or higher. This is because this is a multi-processor box.

How do I see the CPU usage of the individual processors?

How can I do this in real time?

Thanks!

What UNIX are we talking here?

Try mpstat if you're in Solaris or Linux.
