------------------------------------
Summary: 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
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
