Try not to reinvent the wheel. System monitoring is a complex thing. The naive script which pings and mail if there is a problem can be a killer if it is called every minute and you leave for one night.

I suggest to base your work on existing systems: BigBother is nice but does only "instant monitoring", no logs and no way to know when something actually failed. Netup is better since it is a permanently runnong daemon, which knows it already mailed you (it mails - or syslogs, at will - when there is a change, not when there is a problem).
