Yonik Seeley commented on SOLR-10214:
-------------------------------------
bq. Perhaps this is a good opportunity to use the new metrics API here?
Oops, sorry Andrzej, I previously missed this comment.
I don't know anything about the new metrics API yet, and I was just doing some
simple cleanup here in pursuit of SOLR-10205 (I wanted to start tracking
storeFails).
I'll keep this issue open for now in case someone wants to tackle converting to
the new API... we can just tack that onto this issue if it's before 6.5

> 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
