Expose block cache hit/miss/evict counts into region server metrics
-------------------------------------------------------------------
Key: HBASE-3292
URL: https://issues.apache.org/jira/browse/HBASE-3292
Project: HBase
Issue Type: Improvement
Reporter: Jonathan Gray
Assignee: Jonathan Gray
Priority: Minor
Fix For: 0.90.1, 0.92.0
Right now only the hit ratio is exposed into the rs metrics. This value tends
to change very slowly and hardly at all once the cluster has been up for some
time.
We should expose the aggregate hit/miss/evict counts so you can more
effectively see how things change over time.
