It's the same question you asked on Apr 22: https://groups.google.com/d/topic/prometheus-users/KJlEfHqWSdE/discussion
If you can't get SNMP to work with a Fortigate using snmpwalk, then I'm afraid this is not an issue with Prometheus. I suggest you either try your vendor for support, or a discussion group for Fortigate firewalls: e.g. https://forum.fortinet.com/ -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
