> Key: KAFKA-9292
> URL: https://issues.apache.org/jira/browse/KAFKA-9292
> Project: Kafka
> Issue Type: Improvement
> Reporter: Colin McCabe
> Assignee: Colin McCabe
> Priority: Major
> Fix For: 2.6.0
>
>
> 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.
