stack commented on HBASE-2888: ------------------------------ Setting hbase.period in hadoop-metrics.properties doesn't seem to have an effect; counts are off. Here's what I noticed digging in code: 'hadoop-metrics.properties' gets read up into a metrics attributes map but nothing seems to be done w/ them subsequently. Reading up in hadoop, in branch-0.20/src/core/org/apache/hadoop/metrics/package.html, it seems to imply that we need to getAttribute and set them after we make a metrics Context; i.e. in this case, call setPeriod in RegionServerMetrics, etc.? More broadly, need to make sure settings in hadoop-metrics.properties take effect when changed. > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
