Description

Ensuring that the Kafka Controller is healthy is an important part of monitoring the health of a Kafka Cluster. However, the metrics currently exposed are not sufficient for reliably detecting issues like slow progress or deadlocks. We propose a few new metrics that will solve this issue. Even though KAFKA-5028 will potentially fix existing deadlocks, there will still be known (and potentially unknown) issues that can cause slow or no progress so these metrics will still be useful.
