Personally, I have a little monitoring script I wrote that watches the 
cluster resources, local hardware (via the IPMI BMC), UPSes and 
what-not. It loop every 30 seconds and sends an email if/when anything 
of note changes. A node being fenced certainly raises a flag and emails 
go out.

My script is principally for cman + rgmanager, but it should be easy to 
craft your own, too. I just read in the current state of things, compare 
against the values in the last scan, decide whether to send an email or 
not, copy the just-read values over to the last-scan values and delete 
the "new" values and go back to sleep for 30 seconds.
