CPU usage reports

[gphillip at kaiser.aafp.org]

Hi,

I am trying to find a way to get a report on CPU usage by program.  I am
running apache, ldap, qmail, mysql and a bunch of perl scripts.  What I
would like to do is have something monitor CPU use for a full day then
spit out a report saying what percent of CPU was used by each program.

I can use top to get a current look at CPU usage, but does anyone know of
something that will monitor and collect stats over time?

thanks
