Enabling detailed inbound/outbound network queue metrics

[Sergii Mykhalchuk]

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.
