The last few weeks I have noticed a large amount of traffic on the Network Monitor coming from IPSec-ESP. I moved several VPN tunnels off our old WatchGuard to our Palo Alto PA-3020 around the time this started. When I click on the application itself to filter it I see that it cannot identify anything about the traffic. Is this normal? Shouldn't it at least be able to identify the source or destination of the traffic?

Is there any active session present on this PAN FW..? You may apply below mentioned CLI command:
> show session all filter protocol 50
ACC will give you the live session information, where traffic log will give you session information at the start or end.

ESP traffic is encrypted, hence, you would not be able to see the content of the packet. There might be an another possibility, if users are conneting through any VPN client, in that case also, firewall will identify as ESP traffic.

Yeah that's what I figured but it just seems weird it can't even tell where it's coming from. No VPN clients in this case. Just regular VPN tunnels.

To get source and destination information of traffic, go to Monitor > Traffic > Type application "IPSec-ESP". You will find number of logs.
You will have to take Educated guess to find out origin of the traffic.
If Origin of the traffic is your own firewall, than dont worry its intended IPsec Traffic.
If not than there should be something behind the firewall, try to locate IP.

You are correct. The ACC report will not show the traffic details i.e source, destination etc. As HArdik said, you can filter traffic in Logs to get details information.
Hope this helps.
