Subject [jira] [Created] (HBASE-4809) Per-CF set RPC metrics
Date Thu, 17 Nov 2011 04:50:51 GMT
Per-CF set RPC metrics
----------------------

                 Key: HBASE-4809
                 URL: https://issues.apache.org/jira/browse/HBASE-4809
             Project: HBase
          Issue Type: Improvement
            Reporter: Mikhail Bautin
            Priority: Minor


Porting per-CF set metrics for RPC times and response sizes from 0.89-fb to trunk. For each
"mutation signature" (a set of column families involved in an RPC request) we increment several
metrics, allowing to monitor access patterns.  We deal with guarding against an explosion
of the number of metrics in HBASE-4638 (which might even be implemented as part of this JIRA).
