Subject Need Document and Explanation Of New Metrics Name in New Java Producer on Kafka Trunk
Date Tue, 09 Sep 2014 21:07:20 GMT
Kafka Team,

Can you please let me know what each of following Metrics means ?  Some of
them are obvious, but some are hard to understand. My Topic name is
*TOPIC_NAME*.



can we enforce a Topic Name Convention or Metric Name Convention.  Because
in previous version of Kafka, we have similar issue of parsing Kafka
Metrics name with host name issue (codahale lib) .  I have topic name with
“.”  So, it is hard to distinguish metric name and topic.   Also,  when
guys get chance I would appreciate if you guys can explain metric
description on wiki so community would know what to monitor.  Please see
below for full list of metrics from new producer.


Thanks,

Bhavesh
