Subject [jira] [Commented] (OAK-3698) Make it easier to monitor state of observation queue
Date Mon, 29 Feb 2016 14:47:18 GMT

    [ https://issues.apache.org/jira/browse/OAK-3698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15171934#comment-15171934
] 

Teodor Rosu commented on OAK-3698:
----------------------------------

In the OAK-3478 and OAK-3654 context: 

IIUC: This improvement translates to exposing the stats already available for observation
/ event listeners ( ConsolidatedListenerMbean and others ) using the new oak core stats api
( OAK-3654  ). This should simplify monitoring with external tools.

> As suggest offline by [~ianeboston]:
> expose some stats (not time series!) to make it easier to monitor the state of the observation
queue, in particular:
> * number of items in queue
> * number of items entering queue
> * number of items leaving queue
> * percentage of queue size compared to the upper limit by when events get collapsed
