[jira] [Commented] (KAFKA-1251) Add metrics to the producer

    [ https://issues.apache.org/jira/browse/KAFKA-1251?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15815649#comment-15815649 ] 

Andrey commented on KAFKA-1251:
-------------------------------

Hi,

Does anyone knows why "counter" metrics exposed as "rate"? With such aggregation it's not possible to correctly render over different timespans. See implementation in Kibana/Elastic:
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-derivative-aggregation.html

General idea: 
1) expose metrics as counter.
2) render tools take constantly growing number and calculate derivative over requested interval.
