CLI command to see current interface utilization

[amargys]

Hi Guys,

Has anybody knows the command of the interface utilization so I can have an idea how much traffic is going through it? let's say I have a VPN interface and want to know how heavy it's being used. If I could login to the GUI I could easily add a interface monitoring dashboard and see the stats, but I can only access the firewall via SSH.

Thanks,

Augustas

The dashboard is populated with historical data but via CLI you can only read "instant" data.

Instant data will be fine, do you know the command please?
