Subject [jira] [Commented] (CASSANDRA-7384) Collect metrics on queries by consistency level
Date Tue, 22 Jul 2014 21:44:40 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14070960#comment-14070960

Richard Low commented on CASSANDRA-7384:
----------------------------------------

Having relative counts per consistency level helps clients to check rates are as they expect.
Also having the relative latencies would help to estimate the cost/benefit of changing consistency
levels. I think it would be helpful.

> We had cases where cassandra client users thought that they were doing queries at one
consistency level but turned out to be not correct. It will be good to collect metrics on
number of queries done at various consistency level on the server. See the equivalent JIRA
on java driver: https://datastax-oss.atlassian.net/browse/JAVA-354
