     [ https://issues.apache.org/jira/browse/HBASE-6213?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-6213.
--------------------------

    Resolution: Later

We have moved away from per-cf metrics (too expensive).  We may move back in this direction at some future time.  Resolving this meantime as 'later'.
