I have run into this issue many times with FirePower deployments. Customers want to see what the interface utilization for each ASA/FTD device is at on the dash board. Ivegone through all the widgets and while I found I can create what looks like it should work, it just shows no data. I looked into sending Netflow data to FirePower MC, however that requires a separate sensor. Is there anyway to see per device interface utilization within FirePower MC for interfaces on managed devices?
