I just figured out that a firewall rule stopped working and outbound xfers are not working form one server to the other. I never would have known had I not been testing something. What is the best practice to alert myself if passive checks haven't been received for a while.

I could use freshness check and check_dummy and set to warning, but that'd alert the normal contacts and not me...hmmmm....suggestions?

Hmmm. Freshness is the way this is supposed to alert. You may be able to write a script that checks status.dat for any passive checks whose "last_update" time is older than a certain time. Run that script as it's own check, make yourself the contact.
Just a thought, though I presume some one may have a better way.
