> Key: KAFKA-2678
> URL: https://issues.apache.org/jira/browse/KAFKA-2678
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 0.8.2.1
> Reporter: Jun Rao
> Assignee: Dong Lin
>
> Currently, the per partition level lag metric can be negative since the last
> committed offset can be smaller than the follower's offset. This is a bit
> confusing to end users. We probably should lower bound it by 0.
