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)}} -- This message was sent by Atlassian Jira (v8.20.10#820010)
