Subject [jira] [Comment Edited] (OAK-5594) leaderboard of consolidated listener stats should show path as well
Date Tue, 07 Feb 2017 10:56:41 GMT

-----------------------------------------------------------

A general remark on this change and on the other data in the consolidated listener stats:
the output when looking at the [system console|http://localhost:8080/system/console/jmx/org.apache.jackrabbit.oak%3Aname%3DConsolidated+Event+Listener+statistics%2Ctype%3DConsolidatedListenerStats]
is indeed very large. Already for the {{ListenerStats}}, but now also for the {{LeaderBoard}}.
I still think having the paths as part of the LeaderBoard is useful. But I'm wondering if
there would be any other option in terms of formatting it in the system console, so that this
becomes manageable again. [~mreutegg], [~chetanm], wdyt, any idea? Generally, should we port
this to 1.6.1?

> The consolidated listener stats has a leaderboard section which sorts the leaders by
cumulative processTime. This is useful information, however the className of the listener
does not always allow to identify the culprit. Consider Sling's JcrResourceListener - which
is created for each (group of) ResourceChangeListener. The leaderboard will only show (a number
of) {{JcrResourceListener}} as the className and not which ResourceChangeListener is underneath.
> Ideally each listener could provide more details as to who is 'behind' itself - similarly
to the [EventListenerMBean.getToString|https://github.com/apache/jackrabbit/blob/27dbe3c81c5b6d67c5fa7a50a53e7450218079a2/jackrabbit-api/src/main/java/org/apache/jackrabbit/api/jmx/EventListenerMBean.java#L33].
But atm that sometimes produces rather a lot of output.
> A simpler way might be to just add a column {{paths}} - that would show the same as in
the {{ListenerStats}} table.
