We're using openNMS to monitor our servers and switches. Works great, but you have to invest the time to set it up. Probably not much work for just a couple hosts. Lots of work for dozens of servers, switches, routers etc. But worth it...

Subject: OT: how to check everything is working
Hi, i've just had an strange scenario, on one of my servers cent os the I/O controller just stoped working, and all FS went to Read Only. I actually check this:
incomming messages waiting
this is reported to a mysql and showed in a webpage.
the problem is that this was working, but the server started rejecting all emails with a 421 error "Can't write to the disk" so all trafic went to the second MTA. so nobody realised that the server was down...
I started a google search and i found this "mailping" http://mailping.sourceforge.net/ but it seems to be a dead project.
so is anyone using something like this? or has any idea?
