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!

If you're using procps top (default on most Linux), that is. Traditional UNIX top doesn't have this feature.

What UNIX are we talking here?

Try mpstat if you're in Solaris or Linux.
