You might try mon, a tool written in perl for monitoring higher level
services. 
It can be integrated in heartbeat to even trigger a failover - or you
could monitor the HA-blackbox from "outside" and pass a trouble
ticket inside the system. Here is an example I once bookmarked:

Check http://www.nagios.org for monitoring.

P.S.  drbd might be the wrong list -> check linux-ha
