Hi @samon 

 

To understand the issue better, could you please share more details? For example:
– A screenshot of Dashboard → Network → Interfaces showing the high outbound bandwidth
– The model of your FortiGate and if you are using traffic shaping, SD-WAN, or VPN
– When this started happening (right after the upgrade to 7.4.3 or later?)

With these details it will be easier to see if it’s just a display issue or real traffic.

 

Regards,

Harry

I'm not sure what anyone else's experience is but I've never had good luck with bandwidth in fortiview. At least not in the interface as a whole. I've always had it show inaccurately, sometimes showing the bandwidths in the TB level. I rely more on the interface widgets for bandwidth usage, or I look at the the individual application or source via the drill down. I also noticed it appears Fortiview in FAZ is more accurate, even when the box itself isn't. Not really sure why.
