> 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
> Priority: Critical
>
> 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 be 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?
