This is not the case :)

You could indeed, as you suggest, create a simple shell script that  
is run from cron to schedule the service checks. It ain't nothing  
special.

SNMP is very versatile, but it's also very cumbersome to use. It  
takes a lot of investigation to figure out all the proper OIDs,  
unless you decide to tie normal Nagios plugins to custom OIDs (which  
is possible and easy). To read more about the use of plugins and  
custom OIDs, read http://www.kilala.nl/Sysadmin/retrieve_custom_snmp.php

If you do not trust NRPE for active checks, you could also run the  
checks through SSH.

Me, I like to use as much passive checks as I can cause it puts most  
of the scheduling work with the clients, thus freeing up the server(s).

Cheers!
