> URL: https://issues.apache.org/jira/browse/KAFKA-17035
> Project: Kafka
> Issue Type: Improvement

>
> Sometimes, there will be some log segments leftover without getting deleted
> as configured. One example is, the config is set to retention.ms = 7 days,
> but there are some log segments stay in storage for more than 7 days. In this
> case, it's difficult to troubleshoot if there is a bug in kafka or something
> wrong in the log segment (ex: max time is wrongly set).
> To help troubleshooting, we could add "trace level" or "debug level" logs
> when doing retentionSize/retentionMs/logStartOffset check for each log
> segment.
