[jira] [Created] (KAFKA-4386) Producer Metrics Explanation

Pratik kumar created KAFKA-4386:
-----------------------------------

             Summary: Producer Metrics Explanation
                 Key: KAFKA-4386
                 URL: https://issues.apache.org/jira/browse/KAFKA-4386
             Project: Kafka
          Issue Type: Bug
          Components: producer 
            Reporter: Pratik kumar


Context :
Kafka Producer 0.8.x

Problem:
Kafka Producer emits metrics regarding request size stats, request latency and rate stats.
But the inherent meaning of the these metrics are not clear. What does this measure?
Is for each producer send request(which contains batches of messages per broker)? OR Is it for a batch of messages defined according to user batching policy? What happens when some application code has multiple async producers to increase performance (how are rate and percentiles measured?)?
