Fix Min/Avg/Max Values for FS Latency Metrics
---------------------------------------------
Key: HBASE-3129
URL: https://issues.apache.org/jira/browse/HBASE-3129
Project: HBase
Issue Type: Improvement
Components: regionserver
Affects Versions: 0.89.20100924, 0.90.0
Reporter: Nicolas Spiegelberg
Assignee: Nicolas Spiegelberg
Priority: Minor
Fix For: 0.89.20100924, 0.90.0
Currently RegionServer FS latency metrics are a little deceiving. Because
fs*Latency is only updated during RegionServerMetrics::doUpdates, you are
really getting the min/max of the latency average over 'hbase.period' instead
of the actual min/max outliers. We should refactor the code so we can display
these outliers and reset them every 'hbase.period'
