Subject [jira] Commented: (CASSANDRA-688) cache refinements
Date Mon, 18 Jan 2010 00:04:54 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12801627#action_12801627
] 

Chris Goffinet commented on CASSANDRA-688:
------------------------------------------

Can you add nodeprobe support for this? I also noticed using JConsole, the MBean for JMXInstrumentedCache
is never exposed anywhere? Can we namespace it in similar fashion of how we do other operations?
