Report for Bandwidth between remote site and HQ.

Good Afternoon!

I am looking to create a report to run every 30 days on the bandwidth between our remote sites and headquarters. I have added IP Groups and under NTA Summary filter on those groups and see the usage details but not bandwidth between the 2. We have tunnels through Meraki between each. I would like to ideally determine what traffic/bandwidth usage is traveling through those tunnels.

Any ideas or suggestions are welcome!

Thanks in Advance!
