Subject [jira] [Comment Edited] (CASSANDRA-7384) Collect metrics on queries by consistency level
Date Fri, 15 Jul 2016 05:20:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15378877#comment-15378877

------------------------------------------------------------------

Generally LGTM - just a one comment:
* we use {{.}} as a separator throughout the metrics. Would be nicer to use a {{.}} instead
of {{\-}} for the metric names (in the constructor initializing the metric maps - e.g. {{new
ClientRequestMetrics("Read-" + level.name())}})

If you're fine, I can fix that on commit.

> 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
