Subject [jira] [Commented] (HBASE-4219) Add Per-Column Family Metrics
Date Mon, 12 Sep 2011 17:58:09 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13102851#comment-13102851

Nicolas Spiegelberg commented on HBASE-4219:

@stack: the hbase version of this patch should be fine, but note that I'm working on an hdfs
bug where the dynamic JMX metrics don't show up with the public hadoop jar but do with our
internal jar.  Give me a little more time here to figure out the problem and clean some small
stuff up on David's original patch.

> Right now, we have region server level statistics.  However, the read/write flow varies
a lot based on the column family involved.  We should add dynamic, per column family metrics
to JMX so we can track each column family individually.
