I installed ganglia, and I think it worked well for hadoop, hbase for I can see hadoop/hbase metrics on ganglia-web.I want to use ganglia to monitor spark. and I followed the steps as following:1) first I did a custom compile with -Pspark-ganglia-lgpl, and it sucessed without warnings../make-distribution.sh --tgz --skip-java-test -Phadoop-2.3 -Pyarn -Phive -Pspark-ganglia-lgpl2)I configured the conf/metrics.properties:(8653 is the port I set for gmond) and restart spark Master and Workervi conf/metrics.properties# Enable GangliaSink for all instances*.sink.ganglia.class=org.apache.spark.metrics.sink.GangliaSink*.sink.ganglia.name=hadoop_cluster1*.sink.ganglia.host=localhost*.sink.ganglia.port=8653*.sink.ganglia.period=10*.sink.ganglia.unit=seconds*.sink.ganglia.ttl=1*.sink.ganglia.mode=multicastsbin/stop-all.shsbin/start-all.sh3) I refreshed my ganglia-web，but I can not see any spark metrics.4) I made a test to verify whether the sinks of ConsoleSink and CSVSink works OK, and the result is OK, I found metrics in logs and *.sink.csv.directoryI searched topic about "ganglia" and "metrics" on the http://apache-spark-user-list.1001560.n3.nabble.com ,spark JIRA and google, but found anything useful.Any one could give me a help or some proposal?
