I am starting to use VyOS and I am found it very interesting product: until now I used PFSense, OPNSense, LEDE, all very good products but I want to try something different.
I like the idea to have only a CLI interface to configure my router (no GUI) but I think would be very useful, even almost indispensable, a Dashboard to get interface and machine stats, interface status and so on.
After all, I do not think I have to configure my router every day.
Not through SNMP, but you could script something out to display the information. There are a number of ways to do this. Since VyOS is just Debian under the hood, you can easily utilize the vast options available.
A web GUI is pretty far down on the list of priorities for the VyOS team I think. Personally, I don’t need or want the complexity that the web GUI brings to the project, but that’s my opinion. I would, however, like an API that I could tap into and get that information.
