throughput metrics in hadoop-2.0.5
lei liu 2013-08-06, 06:17
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=10.232.98.74:8649

I write one programme that call
FSDataOutputStream<eclipse-javadoc:%E2%98%82=hadoop-hdfs/C:%5C/Users%5C/musa.ll%5C/.m2%5C/repository%5C/org%5C/apache%5C/hadoop%5C/hadoop-common%5C/2.0.0-cdh4.3.0%5C/hadoop-common-2.0.0-cdh4.3.0.jar%3Corg.apache.hadoop.fs%28FSDataOutputStream.class%E2%98%83FSDataOutputStream>.hsync()
method once per second.

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 in ganglia is below:
[image: dw62.kgb.sqa.cm4 dfs.datanode.FsyncCount]
I want to know the ganglia how to display the value of MutableCounterLong
class?

Thanks,
