Hadoop NodeManager RPC activity (HADOOP_NODEMANAGER_RPCACTIVITY)
The HADOOP_NODEMANAGER_RPCACTIVITY application class monitors the RPC activities of the NodeManager. The Hadoop KM gathers these attributes by executing the following query:
<NodeManager jmx url>?qry= Hadoop:service=NodeManager,name=RpcActivity.*
where,
<NodeManager jmx url> Java Management Extensions url, http://<<NodeManager name>>:<<NodeManager port>>/jmx
qry is Hadoop by default
service contains the type of the group, for example, DataNode, ResourceManager, JobTracker, ResourceManager, TaskTracker and other available groups
