Review all our metrics
----------------------
Key: HBASE-2888
URL: https://issues.apache.org/jira/browse/HBASE-2888
Project: HBase
Issue Type: Improvement
Components: master
Reporter: Jean-Daniel Cryans
Fix For: 0.90.0
HBase publishes a bunch of metrics, some useful some wasteful, that should be
improved to deliver a better ops experience. Examples:
- Block cache hit ratio converges at some point and stops moving
- fsReadLatency goes down when compactions are running
- storefileIndexSizeMB is the exact same number once a system is serving
production load
We could use new metrics too.
