Currently we are using a couple of custom connetor plugins for our confluent kafka connect distributed worker cluster. One thing that bothers me for a long time is that kafka connect writes all logs from all deployed connectors to one File/Stream. This makes debugging an absolute nightmare. Is there a way to let kafka connect log the connectors in different Files/Streams?
Via the connect-log4j.properties I am able to let a specific class log to a different File/Stream. But this means that with every additional connector I have to adjust the connect-log4j.properties
Thanks
Kafka Connect does not currently support this. I agree that it is not ideal.
One option would be to split out your connectors and have a dedicated worker cluster for each, and thus separate log files.
Kafka Connect is part of Apache Kafka so you could raise a JIRA to discuss this further and maybe contribute it back via a PR?
