Yonik Seeley updated SOLR-10214:
--------------------------------
    Attachment: SOLR-10214.patch

Here's a draft patch that
- removes a lot of the unused metrics
- adds totals for lookups, hits, evictions... the previous metrics only 
reported per-second stats since the last call
- moves the tracking of hit/miss from BlockDirectoryCache to BlockCache

> clean up BlockCache metrics

> 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
