----------------------------------------
Summary: How to detect heartbeat failure between broker/zookeeper
leader
Key: KAFKA-10726
URL: https://issues.apache.org/jira/browse/KAFKA-10726
Project: Kafka
Issue Type: Bug
Components: controller, logging
Affects Versions: 2.1.1
Reporter: Keiichiro Wakasa
Hello experts,
I'm not sure this is proper place to ask but I'd appreciate if you could help
us with the following question...
We've continuously suffered from broker exclusion caused by heartbeat timeout
between broker and zookeeper leader.
This issue can easily detected by checking ephemeral nodes via zkcli.sh but
we'd like to detect this with logs like server.log/controller.log since we have
an existing system to forward these logs to our system.
Looking at server.log/controller.log, we couldn't find any logs that indicates
the heartbeat timeout. Is there any other logs to check for heartbeat health?
