Subject [jira] [Commented] (CASSANDRA-6539) Track metrics at a keyspace level as well as column family level
Date Fri, 14 Mar 2014 17:48:45 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13935320#comment-13935320
] 

Nick Bailey commented on CASSANDRA-6539:
----------------------------------------

It's just slightly easier to do it in C*. The metrics library does nice things like automatically
expose the metric data in multiple ways. And like I said, in the case of huge numbers of column
families (thousands and above), it's less burdensome to do the aggregation in C* than on the
client.

> It would be useful to be able to see aggregated metrics (write/read count/latency) at
a keyspace level as well as at the individual column family level.
