--------------------------------------------
Summary: Fix the negative remote bytesLag and segmentsLag metric
Key: KAFKA-19841
URL: https://issues.apache.org/jira/browse/KAFKA-19841
Project: Kafka
Issue Type: Task
Reporter: Kamal Chandraprakash
* Each broker rotates the segment independently.
* When the leadership changes to the next replica, then the highest offset
uploaded to the remote storage might already be higher than the baseOffset of
the current leader active segment.
* During this case, the {{onlyLocalLogSegmentsSize}} and
{{onlyLocalLogSegmentsCount}} returns 0, so the metrics shows negative value (0
- activeSegment.size).
