Issue/Introduction

No performance data and "Performance Poll" exceptions in the oc.log like this:

(EE-ManagedThreadFactory-default-Thread-56353) Fortinet_4fc67762-bf7d-4f62-be23-e8c352f957f4=Performance Poll [OC_ACQUISITION] TimHttpHelper 743  Error connecting to http://hostname:port/jsonrpc

Environment

DX NetOps VNA 24.3.8

Resolution

Edit the file:
/opt/CA/VNA/collector/<ENGINE_ID>/repository/deviceConfig/Fortinet-Performance.xml

Replace <ENGINE_ID> with the name of your Fortinet engine folder.

After line 30, add the following line:
           <Value id="FortiManagerUsername">${FORTIMANAGER_HOST_USERNAME}</Value>

As a result, lines 28–32 should look like this:
         <Input>
             <Value id="FortiManagerToken">${FORTIMANAGER_TOKEN}</Value>
             <Value id="FortiManagerHost">${FORTIMANAGER_HOST}</Value>
             <Value id="FortiManagerUsername">${FORTIMANAGER_HOST_USERNAME}</Value>
         </Input>

The same change must also be applied to the file:
/opt/CA/VNA/plugins/Fortinet Plugin/opencollector/repository/deviceConfig/Fortinet-Performance.xml

Then restart the Engine

systemctl restart wildfly
