Subject [jira] [Commented] (AMBARI-9612) AMS : Kafka Metrics - Log flush status metrics do not show up.
Date Fri, 13 Feb 2015 17:37:11 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-9612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14320422#comment-14320422
] 

Florian Barca commented on AMBARI-9612:
---------------------------------------

There are 2 sets of changes:
1. Changes in the metrics definition. The Log Flush metrics have a different structure compared
to the rest of the Kafka metrics. There are members like min, max, mean, median, stddev and
various percentiles, unlike the other metrics groups in Kafka, which have members like 1MinuteRate
etc.
2. Changes in the UI. Now supplying the Log Flush Status widget data from the correct metric.
