---------------------------------
[KAFKA-15801|https://github.com/apache/kafka/pull/14799]
> improve Kafka broker/NetworkClient logging for connectivity issues with
> hostname and port info and higher severity
> ------------------------------------------------------------------------------------------------------------------
>
> Key: KAFKA-15801
> URL: https://issues.apache.org/jira/browse/KAFKA-15801
> Project: Kafka
> Issue Type: Improvement
> Components: logging
> Affects Versions: 3.6.0
> Reporter: Alexander Kilian
> Assignee: johndoe
> Priority: Trivial
>
> When a component of the Kafka broker tries to reach another broker within the
> cluster the logging should be more elaborate and include the IP/hostname and
> port it tries to connect to, and have a higher severity WARN rather than INFO.
> Current logging:
> {{[2023-11-09 07:33:36,106] INFO [TransactionCoordinator id=1] Disconnecting
> from node 1 due to socket connection setup timeout. The timeout value is
> 26590 ms. (org.apache.kafka.clients.NetworkClient)}}
> Suggested logging:
> {{[2023-11-09 07:33:36,106] WARN [TransactionCoordinator id=1] Disconnecting
> from node 1 on kafka-headless.m2-mgex.svc.cluster.local:9093 due to socket
> connection setup timeout. The timeout value is 26590 ms.
> (org.apache.kafka.clients.NetworkClient)}}
