kafka-consumer-perf-test error when printing metrics
Hi,
I'm using kafka-consumer-perf-test but I'm getting an error if I add the --print-metrics option.
Here's a snippet of my output including the error:
consumer-fetch-manager-metrics:fetch-size-max:{client-id=consumer-perf-consumer-99250-1} : 0.000
consumer-fetch-manager-metrics:fetch-throttle-time-avg:{client-id=consumer-perf-consumer-99250-1} : 0.000
consumer-fetch-manager-metrics:fetch-throttle-time-max:{client-id=consumer-perf-consumer-99250-1} : 0.000
consumer-fetch-manager-metrics:fetch-total:{client-id=consumer-perf-consumer-99250-1} : 72.000

Does anyone have the same issue? Am I doing something wrong?

I forgot to mention I'm using Kafka 2.4.0.
