Steps to reproduce:

1. Import the latest 'Fortigate by HTTP' template.
2. Create a new FortiGate host with multiple VDOMs.
3. Click on Dashboards --> the new host --> Network Interfaces or SD-WAN

Result:
Everything not belonging to the root VDOM (default management VDOM) will not be displayed.
Subinterfaces assigned to another VDOM won't be displayed as well.

Expected:
As the default "root" VDOM is used for management, all traffic VDOMs should be included as the main priority for monitoring.
