MetricsRate is missing "registry" parameter
-------------------------------------------
Key: HBASE-2068
URL: https://issues.apache.org/jira/browse/HBASE-2068
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.2
Reporter: Lars George
Assignee: Lars George
Priority: Minor
Fix For: 0.20.3, 0.21.0
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:
{code}
# 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
{code}
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.
