When changing the interface with the command vnstat --iface it shows me the following error Error: Interface for --iface missing.

  • --iface requires an argument - the interface you are going to be looking at. What's the full command you're executing? – Thomas Ward Dec 02 '20 at 19:08

    it show me this ------ andy@andy-pc:~$ vnstat --iface usb0 Error: Interface "usb0" not found in database. – Andy Romero Dec 02 '20 at 19:21
  • the interface has to be an interface on the system. Is usb0 an actual interface on the computer? Usually, that's not how network interfaces are named. – Thomas Ward Dec 02 '20 at 20:13

    Assuming that your wired network interface is eth0, first you must --add that interface to the vnstat database, then you can get stats on it, after it's had some time to accumulate data. See man vnstat for more info, and see the examples at the end of the man page. – heynnema Dec 02 '20 at 20:16
