Where can arguments go?

Ah, I had never thought to setup dependency relationships like that for the
sake of notifications. But that makes sense - getting one notification
about the switch is better than tons of false notifications about the
services behind the switch!

I do know that one service failure will NOT cause the whole host to be
marked down, unless the host's check_command also fails. But as you explain
below, that could still succeed due to admin error. So I do believe you
have the right idea.

One goal here is to eliminate reports of multiple services being down from

Thanks for explaining your reasoning! Maybe I'll be motivated to rethink my
own configuration a bit.
