I would like to have a command-line interface so I could pass arguments more easily to NTM and to make all the process of network topology discovery automatic and not depend on a GUI that has to be operated manually.
I wish I could up vote this more than once.
Since I needed this feature I decided to implement it on my own. So I have made a Ruby script to automate the creation of a scan using AutoIt for Windows (You need to download it and install it before running the script). I have the project on GitHub (GitHub - twix14/NTM-CLI: This is a CLI for SolarWinds Network Topology Mapper, made with AutoIt ) so you can use it (I haven't made a lot of tests so it will probably have some bugs). I only tested it on Windows 10 but if there's any need to make it work on Windows Server or any other version of Windows I can add that version.
