--------------------------------------
To get above details so far I use the Groovy script at [1] to get all details
(it relies on reflection and implementation details). The output provided is
like below

> Consolidated JMX view of all EventListener related statistics
> -------------------------------------------------------------
>
> Key: OAK-2755
> URL: https://issues.apache.org/jira/browse/OAK-2755
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Reporter: Chetan Mehrotra
> Assignee: Chetan Mehrotra
> Labels: monitoring, observation
> Fix For: 1.0.13, 1.3.0
>
>
> Oak Observation support exposes a {{EventListenerMBean}} [1] which provide
> quite a bit of details around registered observation listeners. However in a
> typical application there would be multiple listeners registered. To simplify
> monitoring it would be helpful to have a _consolidated_ view of all listeners
> related statistics.
> Further the stats can also include some more details which are Oak specific
> * Subtree paths to which the listener listens to - By default JCR Api allows
> single path however Oak allows a listener to register to multiple paths
> * If listener is enabled to listen to cluster local and cluster external
> changes
> * Size of queue in BackgroundObserver
> * Distribution of change types present in the queue - Local, External etc
> [1]
