Subject [jira] [Commented] (HDFS-6747) Display the most recent GC info on NN webUI
Date Fri, 25 Jul 2014 07:47:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6747?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14074178#comment-14074178

Haohui Mai commented on HDFS-6747:
----------------------------------

I think that it will be quite handy to show some GC metrics on the UI. Arguably this is not
the best way to operate the system, but GC configuration / metrics are the first things that
we looked at whenever we encounter performance problems.

It is quite helpful to have them on the UI to quickly diagnose performance issues.

> It will be handy if the recent GC information is available on NN webUI. admins don't
need to dig out GC logs.
