Adding NotificationFilters to the listeners of JBossMonitor

gabramovic Sep 9, 2004 5:39 AM

I have been looking into using JBoss monitoring framework for my services over past few days. I have noticed that there is no way of adding NotificationFilters to the listeners of ThresholdMonitor via the deployment descriptor. Am I correct, or I am just shortsighted?

I know that I cam always subclass the ThresholdMonitor and override the
setAlertListeners method from the JBossMonitor. I don't mind patching the change to JBoss Monitor and contribute it back if some of you (Bill) think it would be a good idea.

I believe it is a bit strange how the jboss monitors have been implemented.

Instead of the listeners registering themselves with the broadcaster, the broadcaster registers the listeners!

If you want to play with notifications take a look at:

org.jboss.monitor.services.NotificationListener and its baseclass

http://www.jboss.org/wiki/Wiki.jsp?page=ExampleMinimalNotificationListener

You can even use this external MBean (say X) to subscribe listener MBean (L) for arbritrary notifications from any number of broadcasters using type filtering too, supporting also dynamic subscriptions/unsubscriptions (thus solving any dependency problems)
