Kafka adopt two measurement systems

[张占昌 <zz...@163.com>]

Hello!
Why does Kafka adopt two measurement systems? One is yammer, and the other is its own metric.

Hi, Zhanchang,

We started with Yammer metrics on the broker side. When we developed java
clients, we wanted to reduce external dependencies. So, we added Kafka
metric and used it in the clients. Eventually, we could consider
consolidating the broker side metrics with Kafka metrics too. Currently,
the Histogram support in Kafka metric is not as accurate as the one in
Yammer. We probably need to evaluate whether it needs to be improved before
using it more widely.

Thanks,

Jun
