Michael Coon commented on KAFKA-3564:
-------------------------------------
Hmm, Sum wasn't available when I did a clone on the codebase. I'll have to
update and see if that fits the bill. So what does count represent in metric
terms then? If it were a kind of "instance" snapshot type of count--like "how
many of X are in memory right now", cool; but there is no way to decrement the
count so not sure how valuable it would be. Anyway, I'll check the sum metric
out. Thanks!
> Count metric always increments by 1.0

> 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.
