Github user zentol commented on the issue: https://github.com/apache/flink/pull/4187 I don't think it matters to much whether a metric is completely measured by Flink or just forwarded from kafka classes. Having "kafka" in the name also introduces an inherent redundancy, since the scope for, say the KafkaConsumerThread, already contains "KafkaConsumer".
