[jira] [Commented] (YARN-2599) Standby RM should also expose some jmx and metrics

    [ https://issues.apache.org/jira/browse/YARN-2599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14219307#comment-14219307 ] 

Rohith commented on YARN-2599:
------------------------------

I do agree that StandBy RM should expose jmx and metrics. I did some analysis by comparing /jmx for active rm's and standby rm's(with private patch). All the metrics that were listed in /jmx are consistent with Active details and standby details. But I could not find any details when "/metrics" page when I tried from browser's(IE,chrome and fairefox).It displayed empty page!!! . I think /metrics details are embedded in /jmx only.

> YARN-1898 redirects jmx and metrics to the Active. As discussed there, we need to separate out metrics displayed so the Standby RM can also be monitored.
