Mark Miller commented on SOLR-6752:
-----------------------------------
bq. Where should I look to make sure this is getting registered?
I fired up Solr on HDFS with JMX enabled and took a look at the exported mbeans
with JConsole. I did not see anything for the block cache.
I'd look at how SolrResourceLoader adds the plugins that it loads to the
JmxMonitoredMap.

> Currently, {{o.a.s.store.blockcache.Metrics}} has fields for tracking buffer
> allocations and losses, but they are never updated nor exposed to a receiving
> metrics system. We should do both.
