how to get the config property details of kafka consumer group

1k Views Asked by At

I'm new to kafka, Im facing a issue with consumer group I have a logstash consumer group which created long ago now when I created a new Kafka topic starting with solr* it is automatically adding into kafta consumer group "logstash" If I create any other topic with some other name it is not adding into that consumer group so I would like to know how can I find the config properties information for a consumer group. I'm suspecting a config is provided for this consumer group at the time of creation. This is kafka 0.10

This might not be the best way to do this.

You can simply restart any consumer in this consumer group. Kafka prints all the consumer config property used at the start of the application. If I remember correctly it prints all these logs at INFO level. So please adjust your logger to produce logs at INFO level or a level lower than INFO (probably DEBUG or TRACE) and you will be able to see what is the configuration property that it is using.
