That's bad. Let's see if we can fix that...

No, even if you don't know it yet, you want nagios to do something.

A useful setup takes passive checks which typically report ok status.The 
active check commands return error status. They are executed when the 
passive check results get stale. Without an active check producing an 
error you would never be notified of stale passive check results, which 
in turn means you wouldn't need nagios at all :-)

Of course, you disable active service checking.

Details are in the manual.
