Thank you.
I am writing a nox module which used as a router. And I want to create a queue for \
each port and monitor it.? When the length of the queue is more than a certain limit, \
the router will change another way to forward the packet.? So I must let NOX know the \
status of queue in each port. Do you have any good idea to do this?

You just asked that same question.? The answer remains the same: OVS
doesn't provide a way to monitor the length of a queue.
