Fortigate doesn't display the saturating applications in fortiview

[arnaudnpago]

Hello,

I've a newly deployed Fortigate 200F in my LAN. I've an internet souscription bandwith of 16M.

Recently I've been realizing that my bandwith is constantly saturated, but Fortiview doesn't show me the applications that saturate the bandwith.

As you can see on the images above, the total bw of the internet applications displayed by the firewall (4Mbps) is much lower than our subscription (16Mbps) but it still displays our bw saturated, and the internet service is slow.

Please note that this is not permanent. It happens constantly.
When look to the security report, the firewall doesn't indicate any malicious attack.

Please any help will be very appreciated.

Thanks

Hi @arnaudnpago, 

You mentioned that your internet subscription bandwidth is 16Mbps. Is it for download and upload? 

In the fist image, inbound bandwidth is already 15.96Mbps. Is that the Bandwidth of your internal interface? 

Under FortiView Applications by Bandwidth, Windows.File.Sharing_Read.File alone already consumes 6.50Mbps of the bandwidth plus other applications.

Hi @hbac  

thank you for your reply

16Mbps for download

15.96Mbps is the bandwidth of the WAN interface not internal interface.

Windows.File.Sharing_Read.File is a local network service, so 6.50Mbps is the bandwidth of his internal traffic not internet traffic.
