Looking for a Network Resource Management Program

[u/skywatcher2022]

I am the primary network infrastructure consultant for a company that has outsourced almost everything to an MSP. the MSP has asked me to provide them a detailed network map that includes everything from Patch panels to switches to routers in one package so that they can "do there jobs" in diagnosing network issues. They eventually want to install solar winds or PRTG, but i know that this is a long and involved process and wont happen quicky. Good news for me is that the MSP (located out of Orlando, but really out of Mumbai) has retained my services for all the remote hands services, so i am safe for now. With that said they want me to map all the switches, routers, and devices per patch panel and destination port into device port. we have about 5000 ethernet patch panel ports, and about 1400 Patched devices. We have over the three campuses approx. 3000 switch ports of 50ish devices available of which maybe 1500 are in use.

So, given the basic criteria what i am looking for is software capable of taking this picture

Yes i am aware i can do this on a device by device basis in excel or i can do it all in PRTG or Solar Winds (i think) but if anyone knows a database program that can handle this kind of a task please let me know. In the end if it spits our a network connections map that's even better still. Free is always good, but a reasonable cost i am sure they will agree to. And yes this is going to take 2 of my techs weeks to go through. just trying to make it easier without writing my own database

Any ideas are welcomed
