---------------------------------
Summary: Per topic consumer metrics missing in new consumer
Key: KAFKA-3233
URL: https://issues.apache.org/jira/browse/KAFKA-3233
Project: Kafka
Issue Type: Bug
Reporter: Yifan Ying
In version of 0.8.2.1, the old consumer will provide the metrics reporter
per-topic consumer metrics under group 'ConsumerTopicMetrics'. For example:
*.ConsumerTopicMetrics.clientId.[topic name].BytesPerSec.count
*.ConsumerTopicMetrics.clientId.[topic name].MessagesPerSec.count
These consumer metrics are useful since it provides consumer rate for each
topic. But the new consumer(0.9.0.0) doesn't expose per topic metrics anymore,
even though I did find sensor objects in consumer metrics object collecting
per-topic metrics.
