1、取自ResourceManager REST API’s指标；

https://hadoop.apache.org/docs/r2.8.4/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html

http://<rm http address:port>/ws/v1/cluster/metrics

http://**.**.***.208:8088/ws/v1/cluster/metrics

集群节点状态信息指标

2、取自hadoop的jmx指标

1、资源使用情况指标

http://**.**.***.208:50070/jmx?qry=Hadoop:service=NameNode,name=NameNodeInfo

http://**.**.***.209:50070/jmx?qry=Hadoop:service=NameNode,name=NameNodeInfo

2、负载情况

http://**.**.***.208:50070/jmx?qry=Hadoop:service=NameNode,name=FSNamesystem

http://**.**.***.209:50070/jmx?qry=Hadoop:service=NameNode,name=FSNamesystem

3、对于每个RPC服务监控指标

http:///**.**.***.208:50070/jmx?qry=Hadoop:service=NameNode,name=RpcActivityForPort8020

http:///**.**.***.209:50070/jmx?qry=Hadoop:service=NameNode,name=RpcActivityForPort8020

"RpcProcessingTimeAvgTime" : ,

"CallQueueLength" : 0
