This template is for Zabbix version: 7.0
Also available for: 6.4 6.0

FortiGate by HTTP

Overview

This template is designed for the effortless deployment of FortiGate monitoring by Zabbix via HTTP and doesn't require any external scripts.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • FortiGate v7.4.0

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

  1. On the FortiGate GUI, select System > Admin Profiles > Create New.
  2. Enter a profile name (ex. zabbix_ro) and enable all the Read permissions. Please note the profile name, it will be used a bit later.
  3. Go to System > Administrators > Create New > REST API Admin.
  4. Enter the API-user's name and select the profile name you created in step 2.
  5. The trusted host can be specified to ensure that only Zabbix server can reach the FortiGate.
  6. Click OK and an API token will be generated. Make a note of the API token as it's only shown once and cannot be retrieved.
  7. Put the API token into {$FGATE.API.TOKEN} macro.
  8. Set your FortiGate GUI IP/FQDN as {$FGATE.API.FQDN} macro value.
  9. If FortiGate GUI uses HTTPS, put https value into {$FGATE.SCHEME} macro and 443 into {$FGATE.API.PORT} macro.
  10. If FortiGate GUI port differs from the standard one, specify it in {$FGATE.API.PORT} macro.

Please, refer to the vendor documentation about the FortiGate REST API Authentication.

Trigger prototypes for SD-WAN members discovery

Name Description Expression Severity Dependencies and additional info
FortiGate: SD-WAN [{#ZONE}]:[{#NAME}]: Link down

This trigger expression works as follows:
1. It can be triggered if the interface status is down.
2. {$SDWAN.MEMBER.IF.CONTROL:"{#NAME}"}=1 - a user can redefine context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.
3. {TEMPLATE_NAME:METRIC.diff()}=1 - the trigger fires only if the interface status was up to (1) sometime before.

WARNING: If closed manually, it will not fire again on the next poll because of .diff.
