I'm an aspiring network admin (read: noob), and just started on a new position in IT Operations with a manufacturing co. One of my assigned projects is to get their old (very) outdated asset spreadsheet updated. So rather than going around to every piece of equipment, I'd love to use one of those network diagram tools. Unfortunately I'm unfamiliar with such things, so I wanted to ask for suggestions on what to use. I don't need something to manage everything under the sun, I just want it to show me whats out there so I can keep track. The simpler the better, for the time being anyway. Low cost is a big plus as well. Would appreciate your input.
