HP UX Health tips

Hello Experts,

I know little to nothing about Unix and one of the other departments has charged us with monitoring about ten HP boxes with HP open view. Every now and then we get a warning or a critical so we pick-up the phone and call a Unix tech at all hours of the night. Before we call we ping the server in question then we log on and get a prompt and type ls -l and so I guess we do know a little somthing. We would however like to do more, say check running process, check and errors or services that may have died? What four or five things should we do before we call.

Thanks
