Well I wasn't looking for it :) I reinvented it, because I needed to 
learn the shell a bit better than I knew at that time.

I hope that there are alternatives out there.. :).

I think you would like to continuously monitor your services, not just 
on those early morning hours. Continuous monitoring is nice thing.
Take munin as example, it has two ports, munin-main (as master doing all 
the work) and munin-node (small daemon listening on port 4949 - 
configurable - just providing information for munin-main on demand).

Also nagios could be (recommended) running its main part outside that 
one heavyused server.

Cheers,
Martin
