Hi all, We implemented a MetricsReporter to collect metrics from the new producer and the new consumer. For the producer, we did see a bunch of topic specific metrics under "producer-topic-metrics" group. But the consumer seems not providing any per topic metrics. All I saw are consumer-metrics, consumer-coordinator-metrics and consumer-node-metrics. These look like overall metrics for a KafkaConsumer instance. I tried to look into the code. The consumer's 'metrics 'object seems have sensors collecting per topic metrics, but I am not sure how these metrics are not reflected in those KafkaMetrics inside the metrics object. Is there anyway to get topic specific metrics for consumers, for example, consume rate for a topic.
Thanks. -- Yifan
