Subject [jira] [Commented] (HDFS-5350) Name Node should report fsimage transfer time as a metric
Date Wed, 11 Dec 2013 00:53:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13844884#comment-13844884
] 

Jimmy Xiang commented on HDFS-5350:
-----------------------------------

Instead of some sliding window metrics, I will add two MutableRate metrics for fsimage upload
and download latency.  From these information, we can tell if fsimage transfer is normal or
not too.

> If the (Secondary) Name Node reported fsimage transfer times (perhaps the last ten of
them), monitoring tools could detect slowdowns that might jeopardize cluster stability.
