[jira] [Updated] (OAK-1484) additional observation queue jmx
attributes
[ https://issues.apache.org/jira/browse/OAK-1484?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Dürig updated OAK-1484:
-------------------------------
Description:
The following jmx attributes would be very useful to have, when debugging problems or checking the health of observation listeners and queues at runtime:
* length of an observation listener's revision queue
* duration of stay of oldest revision in an observation listener's revision queue
Especially the second point can be used to judge if an observation listener is 'healthy' or not: eg if the duration is a few seconds, things are probably fine. If the duration is over a minute, then that could raise a flag.
