Network overview / documentation

I have been searching for while now for goed software to document my network setup. I would like to document my servers, containers, network flow, possibly als store some config files. Also would be nice if it has some auto discovery on my network.

As said, I’ve been through a lot, but never found the tool that I liked. Netbox is nice, but lacks a graphical base. Several tools are just drawing tools that lack auto discovery of the network and seem hard to maintain in the future and can not hold extra information. Same goes for some unl based stuff.

Does anyone have a good suggestion?
