Strange behavior with kafka-consumer-group command

Hi all. so i have created a POC with Kafka on 3 bare metal servers. when i use the ./bin/kafka-consumer-groups to --describe to check the lag i am starting to see some weirdness.
When i re-run this command it will sometimes show that the current off-set of a couple partitions is 0 but if i run it again it can change.
Any insights as to what this would be greatly appreciated :slightly_smiling_face:

I guess there will be consumed and produced form the topics? So it just depends on the time if the producer has already send something before the consumer could commit the new offset. Otherwise it won’t be 0. Or is there a reason is should be 0 always?

Yes there are producers and consumers using this topic, but issue is that it reports 0 sometimes out of no where
