Is there a built in function in PANOS to monitor bandwidth across IPSEC tunnels?
I can pull snapshots between IP's using ACC, but does not provide flow history similar to what Network Monitor does. Even setting up QOS only gives me the current snapshot.
Would NetFlow be able to monitor tunnel traffic?
Netflow works only with physical interfaces. It doesnt work with sub-interface or tunnel.
Kindly refer following document.
At best you can put tunnel interfaces in different zone named VPN and generate custom report as mentioned above.
