Comment 7 for bug 1506567

Shang-Yi Chuang is metering just required to monitor on the 'rfp' interface or also on the 'qg' and 'fg' interfaces.
If it is VM to VM traffic (East-West) then you can monitor everything from the 'rfp-' interface.
Is it also required to monitor the external traffic through the 'qg' and 'fg' interface.
