Troubleshoot on-prem connectivity via Virtual network gateway

Question

we are working with one of our vendors are we have set up a site to site VPN using their own Local network gateways. I believe the traffic is not leaving their DC but they say it is an Azure error. We created the Local network gateways and connection and it tied in to our virtual network gateway. We have three other sites set up this way and they are all working fine. What I am trying to do is prove that traffic from the three other sites are coming but no traffic from their site. Everything I find on monitoring is metrics and graphs and just doesn't break it down by IP address. We are sending logs to Log Analytics but I can't seem to find a KQL query to pull that info Any help would be greatly appreciated.
