Subject [jira] Commented: (HBASE-3667) [metrics] regionserver requests not showing in jmx on cluster start but after an individual server start, it starts to work
Date Fri, 18 Mar 2011 02:13:29 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13008283#comment-13008283
] 

stack commented on HBASE-3667:
------------------------------

So a cluster start in our prod worked in that requests showed in our monitoring tsdb.  I'm
going to make this a trivial issue.  Something is up here but seems like it mostly works and
restart of RS is workaround.

> Last night on one of our clusters I ran into the strange problem where metrics were showing
in jmx, all but request rate seemingly.  Then, I restarted a single cluster member and it
started reporting requests/second.  I did a few others and they started working.  Its strange.
 Gary was helping out and noted that requests is only metric to use new MetricsRate otherwise,
its not clear why it'd go wonky.  This issue is placeholder for figuring out whats up here.
