I am trying to generate alerts for ports down/disconnected on a Fortigate Firewall. All my SNMP sensors are working and I can initiate a down state on the port that then reflects in PRTG. What I need to know is where is the global setting to set the "Connection Status Handling" to show down as the default on devices added is "Ignore all disconnected states".
I also want to find out the best way to monitor actual Internet connectivity. So for example the port is up (a device is on and the port in the FW is live) but there's no actual Internet connectivity.
