Wan link manager status light monitor

Question

Hello, 
 i have a simple problem. There is a Sophos XG Firewall with two WAN Interfaces. One of them is the main WAN Interface with a Cable. The second one is a backup WAN interface with a mobile backup router. Now there is a problem, that i cannot monitor the WAN link staus. 
 On my sophos XG i can see the status led of all WAN interfaces. If the status icon is green, there is a connection through this WAN interface to the internet. But if this status icon is red, there is no connection to the internet. 
 How can i monitor this kind of the green/red status icon? Or does anyone have another idea, as I also come to my goal. 
 In my comnay we monitor with PRTG Peassler an the prtocol for monitoring is SNMP. Is ther any function for this scenario? 
 Thank you all!

Hi Michael Wand , 
 Thank you for reaching out to Sophos Community. 
 Firewall changes gateway status to green/red based on the condition set in failover rules. 
 You can configure 'Failover rules' in gateway settings to check ping or TCP connectivity with an external IP address. Here is a sample snapshot for reference. 
 
 To monitor interface status on PRTG, you'll need to import the supported interface MIB file.
