Github user zhenzhongxu commented on the issue: https://github.com/apache/flink/pull/4187 @tzulitai **Regarding the metric naming:** Any suggestions on naming conventions for these flink specific metrics? How do you like 'kafkaconnector-commits-succeeded' (component-metric-name) as an example? I personally like hyphen seperators better than camel case for metric names. I'll not include the other proposed metric in this PR just for the sake of simplicity. I also have some opinions on "offset lag" metric, I think this particular metric is more useful when some external entity perform the monitoring (difference of committed offset vs log head), especially in failure situations. **Regarding the implementation:** Thanks for the feedback. I'll explore the more proper implementation suggested, I'll get back to you with a solution or question.
