Simplest thing seems to be to monitor that thing that's breaking and  
use service dependencies to make the services above dependent on the  
newly monitored service.

If you can't monitor that thing, it's a bit more complicated. You want  
to normally receive notifications for the service unless some certain  
threshold count of them is reached. check_cluster could be useful here  
by making all the services above dependent on a cluster service check.  
If you set the check cluster threshold to say 5, I'd expect that you'd  
receive at most 5(ish) notifications (4 for per-service notifications  
+ 1 for check_cluster itself).
