I'm thinking of writing a system monitor that goes through and checks a bunch of critical system states so that when anything critical changes, an email is fired off.

An obvious way of doing this would be to have a timed loop that calls configurable vector of status check routines/command lines, returning the associated state vector, and then seeing which, if any, of the states changed since the last time through and firing off an email containing those changes.

What is the best practice for this kind of thing?
