os-vnstat: Interface?

[defaultuserfoo]

Installing the os-vnstat plugin tells you to put your default interface into it's configuration file before starting the service.  So I looked at what 'vnstat --iflist' said and put pppoe0 as interface.

Then when I looked at the GUI to start the service, I could pick the interfaces, so I picked the WAN interface.  There is no pppoe0 interface in that list.  Now the configuration has a bunch of entries and still starts with 'Interface pppoe0'.  I didn't find any other 'interface' lines in the file.

Is it supposed to be like this or is this now a misconfiguration?

Look at Interfaces > Assignments. Probably WAN is assigned to pppoe0. So they are one and the same. It's a bit unfortunate different subsystems and/or plugins use different identifiers. Since OPNsense introduced that WAN, LAN, ... abstraction layer above the device names IMHO all fuctions should explicitly use these only.
