[jira] [Created] (SOLR-10214) clean up BlockCache metrics

Yonik Seeley created SOLR-10214:
-----------------------------------

             Summary: clean up BlockCache metrics
                 Key: SOLR-10214
                 URL: https://issues.apache.org/jira/browse/SOLR-10214
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Yonik Seeley


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
