This is a copy of a topic I posted in stackoverflow (https://stackoverflow.com/questions/76458064/apache-kafka-consumer-consumes-messages-with-partition-option-but-not-with-g), where I didn't get any answer yet. Searching the web did not yield any helpful reults either. Hence, I am addressing to this mailing list:
I am running a plain Apache Kafka server (version 3.4.1) which I would like to connect to a Telegraf consumer. The Telegraf ```[[inputs.kafka_consumer]]``` plugin has the option to consume by Kafka "group". When staring Telegraf, I get an error message [inputs.kafka_consumer] Error in plugin: consume: kafka server: Request was for a consumer group that is not coordinated by this broker Hence, I started to investigate my setup by using the Kafka console tools and found that when executing ./kafka-console-consumer.sh --bootstrap-server myserver:9092 --topic test --partition 0 and sending messages via ```kafka-console-consumer.sh```, these messages pop up in the console "consumer" window as expected. In contrast to this, when I run ./kafka-console-consumer.sh --bootstrap-server myserver:9092 --topic test --group my-group nothing happens in the "consumer" window. Furthermore, the command ./kafka-consumer-groups.sh --bootstrap-server myserver:9092 --list yields nothing. What do I have to do to cause the consumer with the "group" option to "see" the messages produced to the topic "test"? Ultimately, how can I solve the Telegraf error?
