T.I. I ran jconsole and ended up with the same result for a worker.
That said, if you turn on JMX for the daemons you end up with a new MBean "metrics" (as given by storm.daemon.metrics.reporter.plugin.domain). This is coming from: JmxPreparableReporter. - For nimbus I see stuff like: num-getClusterInfo-calls for thrift calls. - For ui, I see metrics around the REST calls. - For supervisor, currently I only see "num-slots-used-gauge". Someone else please correct me if I've missed something.

But until then, I just wanted to confirm the metrics I have got through JMX and if that is expected. I added the following to *worker.options*: -Dcom.sun.management.jmxremote \ -Dcom.sun.management.jmxremote.port=1%ID% \ -Dcom.sun.management.jmxremote.authenticate=false \ -Dcom.sun.management.jmxremote.ssl=false And I used cmdline-jmxclient <http://crawler.archive.org/cmdline-jmxclient/>'s jar file as: java -jar /tmp/cmdline-jmxclient-0.10.3.jar -:- 127.0.0.1:16700 | grep -v log4j | sort -u The metrics I got were: com.sun.management:type=DiagnosticCommand com.sun.management:type=HotSpotDiagnostic java.lang:name=CodeCacheManager,type=MemoryManager java.lang:name=Code Cache,type=MemoryPool java.lang:name=Compressed Class Space,type=MemoryPool java.lang:name=Metaspace Manager,type=MemoryManager java.lang:name=Metaspace,type=MemoryPool java.lang:name=PS Eden Space,type=MemoryPool java.lang:name=PS MarkSweep,type=GarbageCollector java.lang:name=PS Old Gen,type=MemoryPool java.lang:name=PS Scavenge,type=GarbageCollector java.lang:name=PS Survivor Space,type=MemoryPool java.lang:type=ClassLoading java.lang:type=Compilation java.lang:type=Memory java.lang:type=OperatingSystem java.lang:type=Runtime java.lang:type=Threading java.nio:name=direct,type=BufferPool java.nio:name=mapped,type=BufferPool java.util.logging:type=Logging JMImplementation:type=MBeanServerDelegate None of these seems to be storm-specific and that is kind of expected because storm does not report those metrics to JMX. Can someone confirm if those really are the metrics I should expect or are there more I can get from JMX? Thanks T.I.
