I'm a little worried that my 'mail server' PC is getting overloaded and I am losing emails etc., or that I am having delays in outgoing mail. How can I set up some sort of monitoring to look at CPU, memory and disk usage - preferably in a graphical format.
realtime - use gkrellm
Either run it as an app with the display on your workstation, or set up the gkrellmd server
historical - munin.sf.net Probably packaged for your OS.
