I would guess that the upgrade either disabled SNMP or enabled a Firewall blocking SNMP polling so you should check to see if that happened.
Also, make sure the SNMP community string is set as well as the SNMP version it correct.

The SNMP configuration of Fortigate is correct, it's works with the snmpwalk command but not with NagiosXi.

Thanks

Can you post the output of the snmpwalk command so we can view it to see if the data the Wizard uses is in the output?

After investigation it seems that since version 5.4 the OID IfDescr no longer indicates the name of the interfaces.
The Wizard using IfDescr and not IfName.

It remains to know how to create a new Wizard "Network" querying the IfName.

I always thought that the description field is optional and not needed.

First. can you upgrade to the latest Network Switch / Router wizard?
Go to the Admin > Manage Config Wizards menu, Click on the Check for Updates button and update the wizard.

Then run the Wizard again and in the Monitor Using menu, use Port's Name and check the Scan Interfaces box and run the Wizard.
Do the interfaces show up and does it display the Port Name and does the Service Description field have the same data as the name?
If so, would that work for you?

If the fields do not match, can you screen capture it and post it here?

I took a look at the code and the process that gathers the bandwidth information for the devices uses the Descriptions in the ifDescr OID so you will have to see if Fortigate has a patch to fix it or a way for you to manually add the Descriptions.

Would not it be possible to make a Wizard using the OID IfName ?
