How to detect availability of inactive broker?

Say two brokers, one is active as the master (e.g. holding the exclusive lock
to back end DB), the other is trying to get the lock to be the master.

If the second one for some reason is down, then after some time when the
master is down, there is no one to resume the work!

So question is: how to detect the availability of the inactive broker? as it
is inactive, it is not able to process messages, right?? so it is not
feasible to try to send it msg to test its liveness ..

please share your thoughts.

You could perhaps use JMX to monitor inactive broker?
