[jira] [Commented] (HDFS-13854) RBF: The ProcessingAvgTime and
ProxyAvgTime should display by JMX with ms unit.
[ https://issues.apache.org/jira/browse/HDFS-13854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16589775#comment-16589775 ]
Brahma Reddy Battula commented on HDFS-13854:
---------------------------------------------
thanks for reporting. How about changing monotonicNow()..? i.e START_TIME.set(monotonicNow());,PROXY_TIME.set(monotonicNow());
So that we can remove org.apache.hadoop.hdfs.server.federation.metrics.FederationRPCPerformanceMonitor#getNow..?

> In the FederationRPCMetrics, proxy time and processing time should be exposed to the jmx or ganglia with ms units. Although the method toMS() exists, we cannot get the correct proxy time and processing time by jmx and ganglia.
