Motivation
After we upgraded to 8.2 we no longer are getting events into Kafka. We have 3 dCache instances. One 7.2 remaining still publishing to Kafka with no issue. (#7123).
The issue is that according to spring-projects/spring-kafka#2251, the kafka-clients provide no hooks to determine that a send failed because the broker is down (spring-projects/spring-kafka#2250). This is still not fixed so this should be fixed.
Modification
Change the LoggingProducerListener so that when TimeoutException will be catch, the error message will indicate that there is a connection issue or the broker is down.
Result
Log looks like this
