Anu Engineer resolved HDFS-9692. -------------------------------- Resolution: Duplicate > Report Top Namenode rpc consumers through JMX > --------------------------------------------- > > Key: HDFS-9692 > URL: https://issues.apache.org/jira/browse/HDFS-9692 > Project: Hadoop HDFS > Issue Type: Wish > Reporter: Nikhil Mulley > > Hi, > I think it would really help if namenode(s) through metrics/jmx report the > top rpc consumers, so it will be really handy to look at the rogue clients in > times of despair/troubleshooting times. > At times of rpc spikes on namenode, and callqueuelength increasing, it > becomes tedious to figure out the offenders when there is a huge cluster (>1k > nodes). > Having rpc client information(src_host:src_port) in the top consumers list > would help operators. Let me know if any other information is needed to make > this feature added to namenode metrics system. > thank you > Nikhil -- This message was sent by Atlassian JIRA (v6.3.4#6332)
