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

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.
