[jira] [Created] (KAFKA-9292) KIP-551: Expose disk read and write metrics

Colin McCabe created KAFKA-9292:
-----------------------------------

             Summary: KIP-551: Expose disk read and write metrics
                 Key: KAFKA-9292
                 URL: https://issues.apache.org/jira/browse/KAFKA-9292
             Project: Kafka
          Issue Type: Improvement
            Reporter: Colin McCabe
            Assignee: Colin McCabe


It's often helpful to know how many bytes Kafka is reading and writing from the disk.  The reason is because when disk access is required, there may be some impact on latency and bandwidth.  We currently don't have a metric that measures this directly.  It would be useful to add one.
