When monitoring my Kafka Connect, I am getting wrong values for records-lag, records-lag-avg, records-lag-max. I compare the values from *kafka-consumer-groups* with what I see in JConsole. While the LAG is higher then 0, the records-lag, records-lag-avg, records-lag-max shows 0, Nan, NaN respectively under kafka.consumer > consumer-fetch-manager-metrics > "topic" > "partition". Is this a known issue?
