Hadoop DataNode UGI metrics (HADOOP_DATANODE_UGIMETRICS)
The HADOOP_DATANODE_UGIMETRICS application class monitors the user and group information activities of a DataNode group. The Hadoop KM gathers these attributes by executing the following query:
<DataNode jmx url>?qry=Hadoop:service=DataNode,name=UgiMetrics
where,
<DataNode jmx url> is the Java Management Extensions url, http://<<data node host name>>:<<data node 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
