I'm looking for a little direction on this one. We have 8 mobile servers, and at anytime one can go offline and be moved to a different location. I don't want Nagios to send me an alert if a system goes offline. I would like it to just send an alert on a service, CPU gets to hot, etc. I have everything working fine as of right now, apart from the fact that I get alerts when the system goes down.
As I said these servers are online and offline constantly over the course of a two week period. So getting a message at 3:00AM on a Saturday telling me a system is offline, I can care less about. I'm more concerned about something overheating. So any advice would be appreciated on how to tackle this?
