Description This article describes why there are no graphs on some VLAN interfaces despite having traffic on them.
Scope FortiGate-40F, 60F, 61F, 100F, 101F, 200F and 201F.
Solution

This is not a bug. This is a hardware limitation. The SOC4 hardware table size supports only up to 768 VLAN graphs.

To resolve no graphs on some VLAN interfaces, reduce the number of VLANs to 768 or fewer.

 

Verification:

Ensure that VLAN interfaces with traffic have graphs on them by viewing via the dashboard in the GUI.
