[arcabah]

Description

This article describes how to enable a REST API token to use in the PRTG Monitoring System to monitor the SNMP sensors of FortiGate.

Scope

FortiGate.

Solution

1. Create a REST API Administrator under System -> Administrator, choose a name i.e. 'fortinet', generate an API key, and save the value:
   
   

Note:

Every time regenerate is selected, it will generate a new API key. It must also be re-imported on the PRTG server configuration.

2. On the PRTG server configuration, edit the FortiGate device settings. Under the 'Credentials for FortiGate' tab, add the API token generated on the previous step, and select the 443 port.

Note: Verify the Admin Access Port for the Firewall. If the Admin Access port is different than port 433, use the same port number as the Admin Access port of the Firewall to connect with the PRTG Monitoring system.

3. On the FortiGate device settings in the PRTG server, select the 'Credentials for SNMP devices' tab and select the SNMP v2 version with the Community String 'fortinet' and the SNMP port 161.
   
   

4. As a result, the SNMP sensors like 'FortiGate System Statistics' will be up and running, showing valuable information about the FortiGate statistics.
