Summary: Add metrics to record Router's operations
Key: HDFS-16065
URL: https://issues.apache.org/jira/browse/HDFS-16065
Project: Hadoop HDFS
Issue Type: Improvement
Components: rbf
Reporter: Janus Chow
Currently, Router's operations are not well recorded. It would be good to have
a similar metrics as "Hadoop:service=NameNode,name=NameNodeActivity" for
NameNode, which shows the count for each operations.
Besides, some operations are invoked concurrently in Routers, know the counts
for concurrent operations would help us better knowing about the cluster's
state.
This ticket is to add normal operation metrics and concurrent operation metrics
for Router.
