----------------------------------------
Summary: improve Kafka broker/NetworkClient logging for
connectivity issues
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
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)}}
