Hadoop JobTracker RPC activity (HADOOP_JOBTRACKER_RPCACTIVITY)

The HADOOP_JOBTRACKER_RPCACTIVITY application class monitors the RPC activities of the JobTracker. The Hadoop KM gathers these attributes by executing the following query:

<JobTracker jmx url>?qry=Hadoop:service=JobTracker,name=RpcActivity.*

where,

<JobTracker jmx url>  Java Management Extensions url, http://<<JobTracker name>>:<<JobTracker 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

name contains the type of metrics data you want to collect and display, for example, JVMmetrics, Queuemetrics, RPCactivity and other available metrics types
