Can anyone recommend a Linux program that can produce graphs of CPU usage on a server? I could always write something that runs “uptime” every few minutes and logs the values, then produces some graphs, but I assume someone must’ve made something like this before, and I’d rather not duplicate the effort. I’d like to be able to see CPU load over the course of a day so that I can compare performance after tweaking things. Usage varies widely at different times of day, so graphs would help compare results at various times of day. Something that handles multiple processors would be nice too.

Time to put the 4-core server to use and give W3Counter the relief it needs.
