Gary Helmling updated HBASE-2068:
---------------------------------
Release Note: Converts MasterStatistics "cluster_requests" attribute to a
MetricsRate value (computed as requests / sec). Also adds a "requests"
attribute to RegionServerStatistics MBean, also as a MetricsRate value.
Status: Patch Available (was: Reopened)
This patch adds JMX support for MetricsRate instances, by adding a
MetricsMBeanBase class which understands HBase metrics classes.
> MetricsRate is missing "registry" parameter

> I am trying to get the graphing going using Edward Capriolo's great JMX to
> Cacti [guide|http://www.jointhegrid.com/hadoop/]. I checked and I am missing
> the request rate in the JMX MBean:
> {noformat}
> # sh 0_20/regionserver/RegionServerStatistics.sh
> service:jmx:rmi:///jndi/rmi://foobar:10102/jmxrmi controlRole mypass
> hadoop:name=RegionServerStatistics,service=RegionServer
> storefiles:493 blockCacheFree:139771296 storefileIndexSizeMB:102
> memstoreSizeMB:0 stores:658 blockCacheCount:8400
> regions:83 blockCacheHitRatio:0 blockCacheSize:717478944
> atomicIncrementTimeNumOps:0 atomicIncrementTimeAvgTime:0
> atomicIncrementTimeMinTime:-1 atomicIncrementTimeMaxTime:0
> {noformat}
> I checked the code and the difference between requests and the other
> attributes is that MetricsRate does not register itself in the
> MetricsRegistry used by the dynamic MBean like for example the
> MetricsLongValue does.
