Hi! I'm trying to export metrics to prometheus but can't seem to get the correct value for our numRecordOut for our sources. In the picture I can see that there's records produced, but when querying

flink_taskmanager_job_task_operator_numRecordsOut{task_name=~"Source:.*"}

or

flink_taskmanager_job_task_numRecordsOut{task_name=~"Source:.*"}

they're always zero. What metric name is the flink dashboard using for the value that is visible in the picture?
