records-lag-max

[Chen, Mason]

Hi all,

 

I am having some trouble with the lag metric from the kafka connector. The gauge value is always reported as NaN although I’m producing events first and then starting the flink job. Anyone know how to fix this?

 

```

# TYPE flink_taskmanager_job_task_operator_records_lag_max gauge

flink_taskmanager_job_task_operator_records_lag_max{ … } NaN

```

 

Thanks,

Mason

I removed an unnecessary `.keyBy()` and I’m getting the metrics again. Is this a potential bug?
