Install Nagios which is a framework of Perl scripts designed to do just 
this. You can also monitor servers, databases, printers, whatever. 
Decide when alerts should be sent, like to email during 9-5 or to your 
phone in off hours. It's also do dependency paging so if a server fails 
you won't get ten messages bout each service on that machine failing. 
It's pretty slick.

However, it's a bit complicated to get going. I'm out of town this 
weekend, but I can dig up a recent config and package it a bit for you 
next week if you're interested. Working configs will make getting the 
whole thing up and running much easier.
