Subject [jira] [Comment Edited] (SOLR-10214) clean up BlockCache metrics
Date Tue, 18 Apr 2017 16:30:42 GMT

    [ https://issues.apache.org/jira/browse/SOLR-10214?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15972994#comment-15972994

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

This has been fixed on master as a part of SOLR-9959, but porting it to 6x would be a bit
messy - specifically, I'd like to avoid introducing the {{MetricsMap}} and related MetricsUtils/JMX
changes to 6x.

Edit: I may need to do that (carefully) anyway due to SOLR-10000.

> Many (most) of the block cache metrics are unused (I assume just inherited from Blur)
and unmaintained (i.e. most will be 0).  Currently only the size and number of evictions is
tracked.
> We should remove unused stats and start tracking
> - number of lookups (or number of misses)
> - number of hits
> - number of inserts
> - number of store failures
