Guozhang Wang commented on KAFKA-3564:
--------------------------------------
I see your point now, in that case you can just call {{Rate()}}, which will use
a default {{SampledTotal}} in that class:
https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/metrics/stats/Rate.java#L113
As stated in the java doc "By default this is the total observed over a set of
samples from a sampled statistic divided by the elapsed time over the sample
windows." I think that should work for your case?
> Count metric always increments by 1.0

> Key: KAFKA-3564
> URL: https://issues.apache.org/jira/browse/KAFKA-3564
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.10.1.0
> Reporter: Michael Coon
> Assignee: Kim Christensen
>
> The Count metric's update method always increments its value by 1.0 instead
> of the value passed to it. If this is by design, it's misleading as I want to
> be able to count based on values I send to the record method.
