Subject [jira] Created: (HBASE-1729) Move cache stats out of RS log and into metrics
Date Thu, 30 Jul 2009 23:47:14 GMT
Move cache stats out of RS log and into metrics

                 Key: HBASE-1729
                 URL: https://issues.apache.org/jira/browse/HBASE-1729
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: stack

We log this every minute in RS logs:

2009-07-30 16:24:54,479 DEBUG org.apache.hadoop.hbase.io.hfile.LruBlockCache: Cache Stats:
Sizes: Total=414.8218MB (434972192), Free=252.50949MB (264775392), Max=667.3313MB (699747584),
Counts: Blocks=1106, Access=273562, Hit=271671, Miss=1891, Evictions=0, Evicted=0, Ratios:
Hit Ratio=99.30874705314636%, Miss Ratio=0.691250991076231%, Evicted/Run=NaN

Thats a metric.  Should be over in metrics.  Metrics does some of above but not all.  Extend
it so just as comprehensive.  Then we can see it ganglia, jmx, etc.
