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.
