Subject [jira] [Commented] (HBASE-6717) Remove hadoop-metrics.properties when everything has moved over.
Date Tue, 11 Dec 2012 21:27:21 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13529354#comment-13529354
] 

Elliott Clark commented on HBASE-6717:
--------------------------------------

{code}*.sink.file*.class=org.apache.hadoop.metrics2.sink.FileSink{code}
That says that all sinks in all groups that have a name starting with file till be a FileSink.
 It's an example for how to set the class of a sink.

{code}*.period=10{code}
That says that the period for all groups will be 10 seconds. Meaning everything that changes
will be picked up at most 10 seconds later.  It's the same default that was shipped with previous
versions of HBase.

bq.Also, what do I do if I want other than a filesink? 
Yeah I need to add some examples for things other than file sinks.  I hope to do that in HBASE-7074
along with lots more.

bq.Is JMX always on? Do I have to do anything in here to turn it on?
Nope no work is needed to turn jmx on.  It's on by default.
