Add more metrics to HBase
-------------------------
Key: HBASE-5533
URL: https://issues.apache.org/jira/browse/HBASE-5533
Project: HBase
Issue Type: Improvement
Affects Versions: 0.92.0
Reporter: Shaneal Manek
Assignee: Shaneal Manek
Priority: Minor
To debub/monitor production clusters, there are some more metrics I wish I had
available.
In particular:
- Although the average FS latencies are useful, a 'histogram' of recent
latencies (90% of reads completed in under 100ms, 99% in under 200ms, etc)
would be more useful
- Similar histograms of latencies on common operations (GET, PUT, DELETE) would
be useful
- Counting the number of accesses to each region to detect hotspotting
- Exposing the current number of HLog files
