Hi guys, We have a 3 producers producing for a kafka topic with 3 partitions. We have a scheme were each producer, produces for one partition. All producers connect to all partitions but we ensure that each producer only sends messages for one partition.
The odd thing is that when looking to the producer metrics, kafka.producer:type=producer-node-metrics,client-id=producer-N,node-id=node-X (where N is producer number and X the leader node of the partition it connects to) for the client-id that should not have any message flowing, we get the following values: incoming-byte-rate 876.0695011188626 outgoing-byte-rate 174.53683898779164 request-latency-avg 0.0 request-latency-max -Infinity request-rate 3.356477672842147 request-size-avg 52.0 request-size-max 52.0 response-rate 3.356588126892194 The request-latency-avg, request-latency-max, request-size-avg and request-size-max never change and its values seems to have never being set, but all the others are always changing. This looks like a bug in metrics and we have almost confidence that no messages are flowing through this client-id (which is what we want), but we need to know more why this strange behaviour in metrics. All other clients, were messages are really flowing don’t have this issue and their metrics are fine. Has anyone had this kind of issue ? Thanks all for your help.
