I am currently evaluating Solarwinds Network Performance Monitor with User Device Tracker and Server Application Monitor. So far Solarwinds does a great job at offering an all-in-one product, although it's not really cheap. I looked into PRTG from Paessler, but with it I am not able to find out on which switchport a device is connected to. ManageEngine seems to be able to do it with OpManager + IPAM & SPM, but it seems it's also not really cheap if I intend to also monitor applications on more than 200 servers.
Has somebody maybe experience with both of the two solutions?
