Server CPU usage
Short of knowing what it's called to do a search for it, but I like to know is there a way (script maybe?) that allows a site owner to monitor actual CPU usage on a server (a shared one for example)?Like to know if or when a forum is taking up a lot of resources or not (cPanel isn't descriptive enough, it's general for the entire server -- not how much my forum is using).
Would like to keep an eye on forum performance to make sure it doesn't bog down -- and any mods to the forum script isn't taking up extra unwarranted cycles. Speed is important -- and don't want trouble with the host.
Thanks for any heads up.

Oops, sorry if this is in the wrong forum. :/
