Subject [jira] [Commented] (HDFS-13854) RBF: The ProcessingAvgTime and ProxyAvgTime should display by JMX with ms unit.
Date Mon, 27 Aug 2018 19:54:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16594163#comment-16594163

Íñigo Goiri commented on HDFS-13854:
------------------------------------

Got it, JMX returns by itself whatever we store.
OK, let's go for it.

Just for completeness, can you point to the code in the Namenode or the RPCServer to try to
be as consistent as possible?

> 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.
