thank you for the accurate and full answer,
I'll investigate the scripts and the NRPE features of nagios,
I'm currently using it just for remote tcp and ping monitoring.
Thank you Guys for the nice answers!
They are very useful!

We use Nagios in combination with the Nagios Remote Process Executor
(NRPE) and a handfull of homewritten scripts to:
- - Check remote accessibility of services (that's formal talk for
"setting up a TCP session and checking the output")
- - Checking the local availablility of services (that's formal talk
for "check if the process defined in the /var/run/foo.pid does
exist") on remote machines.
- - Check for the consistency of systems (that's formal talk for "I
expect these processes to be running, and these network cards to
have these media features, and do we have the required BGP
neighbours, and these not more than X users logged in, are the
mailqueues not too full, and etc")
For the 139 devices (FreeBSD machines, Linux machines, switches,
routers, radio links, Windows machines and even serial-to-ethernet
convertors), we monitor 1146 different services. And despite the
huge amount of things, I get on average only 10 messages a day,
mostly from one of the SMTP servers when a neighbouring body is
sending out their daily spam-run to all of their recipients (incoming
mailqueue, CPU load, mail spike :-)
