Disable alerts if $SOME_SERVICE is down

Hello!

I've been trying to find a way to ignore alerts if i.e. xymon's local
connection is down. Currently our xymon -server sends alerts from every
host if the local connection goes down. Unfortunately in our current
setup that's quite possible scenario and things are going to the
direction where the boy cried wolf too often.

So, how I could restrict alerts so, that if local connection (or any
other service for the matter) fails, alerts won't trigger?
