sdn switch buffers status

Hi everyone 

I am trying to simulate a data center network.  My topology with 20 Open vSwitch and 16 end-host create a fat tree topology and everything work fine and I can see the network with links and nodes and flows in controller user interface. The controller is SDN Controller Version:  I generate multiple parallel different flows with D-ITG (one server and multi-client).

How can I see the occupied buffer of each switch by the controller?

Can I save the status of the switches' queues in a log file for a period of time?
