Not if you let the master hobbit send it status to the slave hobbit and check 
the status on the slace hobbit.  If the master hobbit is down, the slave 
hobbit will become purple.  It is possible that you miss some alerts.

If I need to do something like this, I would create a custom test that does 
some more advanced checking (Can I send an alert?  Can I rech my smtp 
server? ...).  The status is send to the other hobbit server and can be used 
to trigger a failover in alerting.
