The --state option, that can also be used with --describe only, reports the group level information that comes back in the response of DescribeGroups API call along with the coordinator id of the group:

$ bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group my-group --state
Note: This will only show information about consumers that use the Java consumer API (non-ZooKeeper-based consumers).
COORDINATOR (ID)       ASSIGNMENT-STRATEGY     STATE          #MEMBERS
localhost:9092 (0)     range                   Stable         3 

In the above outputs, the width of the following columns will be dynamically determined (as opposed to the fixed widths that have been applied so far):

• TOPIC
• CONSUMER-ID
• HOST
• CLIENT-ID
• COORDINATOR (ID)
