> 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.
