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?
