[jira] [Commented] (CASSANDRA-7436) Dtest for tracking metrics regressions

["Steve Wang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-7436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14702013#comment-14702013 ] 

Steve Wang commented on CASSANDRA-7436:
---------------------------------------

Created jmxmetrics_test, which takes JMX metrics and tests whether they work as expected. Unfortunately, I'm not too familiar as to how each value should change, so I only judged their expected change by tracking the change in values a couple times myself.

> We should create a dtest that runs a small load test and collects a bunch of the JMX metrics and introduce assertions to ensure they are roughly the same every time.
