Using SNMP to monitor health check

You can monitor SD-WAN health check related statistics using SNMP. The MIB file can be downloaded by going to System > SNMP and clicking Download FortiGate MIB File.

The following OIDs can be monitored:

This example shows a SD-WAN health check configuration and its collected statistics.

To configure the SD-WAN health check:
config system sdwan
    set status enable
    config zone
        edit "virtual-wan-link"
        next
    end
    config members
        edit 1

            set gateway 192.168.2.1
        next
        edit 2
            set interface "MPLS"
            set zone "SD-Zone2"
            set cost 20
        next
        edit 3
            set interface "port2"
        next
    end
    config health-check
        edit "pingserver"
            set server "8.8.8.8"
            set sla-fail-log-period 10
            set sla-pass-log-period 20
            set members 2 1 3
            config sla
                edit 1
                    set link-cost-factor jitter packet-loss
                    set packetloss-threshold 2
