Re: throughput metrics in hadoop-2.0.5

There is "@Metric MutableCounterLong fsyncCount" metrics in DataNodeMetrics, the MutableCounterLong class continuously increase the value, so I think the value in ganglia should be "10, 20 ,30, 40" and so on. but the value the value is fsyncCount.value/10, that is in "1 ,1 , 1 , 1" in ganglia.

I use hadoop-2.0.5 and config hadoop-metrics2.properties file with below content. *.sink.ganglia.class=org.apache.hadoop.metrics2.sink.ganglia.GangliaSink31 *.sink.ganglia.period=10 *.sink.ganglia.supportsparse=true namenode.sink.ganglia.servers=10.232.98.74:8649 datanode.sink.ganglia.servers=10.23
