Subject [jira] [Commented] (AMBARI-3115) HBase Read/Write request metrics seem to have changed for 2.x stack
Date Thu, 05 Sep 2013 20:09:54 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-3115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13759389#comment-13759389
] 

Srimanth Gunturi commented on AMBARI-3115:
------------------------------------------

HBase in HDP2 stack changed the metric from cumulative to actual counts of read/write. 
Also, these metrics are the actual counts, and not rate of reads/writes.

> See the screenshot for HBase Cumulative Requests graph.
> The graph does not seem like it's displaying cumulative read/write requests, but rather
showing the rate...  so the label no longer makes sense.
> This is on the 2.0.5 stack.  On the 1.x, I believe this graph would show cumulative read/write
requests (which were less useful).
> So for 2.x stack, we should probably change the label for this graph to say Reads/Writes
per Second (or whatever we are showing - need to confirm).
