# 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: 7.4 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](https://www.zabbix.com/documentation/7.4/manual/config/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](https://docs.fortinet.com/document/fortigate/7.4.0/administration-guide/399023/rest-api-administrator) about the FortiGate REST API Authentication.
