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?
