I speak from Brazil so sorry if English is not correct, I hope you understand me.
I have the MSP network monitoring, almost all working 100% the problem I have is that the monitor Internet links, not working because I'm on the firewall and see that the LAN firewall is 10.10.0.254 then I monitor the firewall by proprio probe, and through another probe I monitor the WAN link 200.X.XXX.XXX, externally and learn to monitor network status, but so you can not get the bandwidth consumption, history of falls.
Thank you.
