Cumulative message counts for queues can be enabled by setting the +EnableMessageCounters+ attribute on the ServerPeer MBean declaration (messaging-service.xml in the community distro) or by invoking the enableMessageCounters method of the ServerPeer MBean from the JMX console.  The output can be retrieved from the +MessageCounters+ attribute of the same MBean or by invoking the +listMessageCountersAsHTML+ method.  The deltas in the counters are, I believe (and have been too lazy to dig-up the documentation), the difference since last access of the message counters themselves (of course, deltas are "differences," my uncertainty is the difference from "when to when").

I don't have any knowledge on how this mechanism counts messages for Topic subscriptions because I've never had to diagnose a problem with one.  All of the Topics on my project are very low volume and they've never gone haywire, like JBM queues sometimes are inclined to do.
