Hello guys,

We are trying to track network queues, after enabling 
"taskmanager.network.detailed-metrics” as described in the docs [1], we do not 
see any of *QueueLen metrics from here [2] in our metrics reporter (slf4j for 
debug purposes).

We are using Flink 1.8.0 at the moment.

Do you guys know if it is a known issue or not?

Thanks in advance.
