[infinispan-issues] [JBoss JIRA] (ISPN-3335) JMX statistics for Queries partially doesn't work

[Adrian Nistor (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-3335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12926569#comment-12926569 ] 

Adrian Nistor commented on ISPN-3335:
-------------------------------------

This seems to be caused by a bug in the way MutableSearchFactory of Hibernate Search is reconfigured when new indexable classes are found in cache. A new copy of the factory is created and all configs are copied from the previous. The statistics object is not (including the enable statistics flag) - this was overlooked maybe. This can be immediately worked around in Infinispan by reimplementing the query statistics mbean to not rely on it being copied during search factory reconfiguration, as the original one does. But this is a messy workaround, so I'll file an issue on Hibernate Search and see when can they provide a proper fix.

> I was playing around with Query JMX statistics, and found out that there are several attributes like SearchQueryTotalTime are always 0 (this attr. represents the duration of query in nano-seconds), even though I'm running the infinispan query. 
> The only attribute which is updated and returns proper value is StatisticsEnabled. Also the following operations work as expected: 
>    getNumberOfIndexedEntities(String entity)
>    clear()
> I've tried also to retrieve the statistics using the following method:
> {code}
> Search.getSearchManager(cacheManager.getCache(CACHE_NAME)).getSearchFactory().getStatistics().getSearchQueryTotalTime()
> {code}
> and it returns the same results as if getting via JMX. 
> You can find the whole running test attached.
> Best regards,
