You can still have a look at the - meanwhile legacy - features
ClusterMon-RA and/or
the global cluster properties notification-agent/notification-recipient.

The first should be available in any case and you can find how to use it

The 2nd might not be available/compiled in but if it is this link tells
you how to use it:
