Philip Nee commented on KAFKA-15686:
------------------------------------
[~ihavenoem...@163.com] - What is the use case of knowing which broker is down?
If telemetry is set up for your kafka cluster, you should be able to tell by
looking at the broker side metrics. It would be helpful to articulate a clear
case to help community to understand the rationale behind the ask. Thanks.
