John Roesler created KAFKA-8696: ----------------------------------- Summary: Clean up Sum/Count/Total metrics Key: KAFKA-8696 URL: https://issues.apache.org/jira/browse/KAFKA-8696 Project: Kafka Issue Type: Improvement Reporter: John Roesler Assignee: John Roesler
Kafka has a family of metrics consisting of: org.apache.kafka.common.metrics.stats.Count org.apache.kafka.common.metrics.stats.Sum org.apache.kafka.common.metrics.stats.Total org.apache.kafka.common.metrics.stats.Rate.SampledTotal org.apache.kafka.streams.processor.internals.metrics.CumulativeCount These metrics are all related to each other, but their relationship is obscure (and one is redundant) (and another is internal). I've recently been involved in a third recapitulation of trying to work out which metric does what. It seems like it's time to clean up the mess and save everyone from having to work out the mystery for themselves. I've proposed https://cwiki.apache.org/confluence/x/kkAyBw to fix it. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
