Fortigate

Use prometheus snmp_exporter to get fortigate metrics via snmp.

i used the following generator(generator.yml):

fortigate_snmp:
  walk:
    - ifXTable
    - fgVpn        
    - fgSystem        
    - fgIntf
    - fgInetProto

  max_repetitions: 25
  timeout: 10s
  auth:
    username: your_username  # Required, no default. -u option to NetSNMP.                                                                                                                                         
    security_level: authNoPriv  # Defaults to noAuthNoPriv. -l option to NetSNMP.                                                                                                                                  
                                # Can be noAuthNoPriv, authNoPriv or authPriv.

    auth_protocol: SHA  # MD5 or SHA, defaults to SHA. -a option to NetSNMP.                                                                                                                                       
                      # Used if security_level is authNoPriv or authPriv.       

with the following prometheus config :

  - job_name: 'snmp'

      - targets:
        - x.x.x.x # fortigate device.
    scrape_interval: 3m

      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: snmp_exporter:9116  # SNMP exporter.
