I just drew a 3D coordinate system, mapped out some points and moved every floor of devices up one in the y axis, keeping x and z the same. That would be a PITA with as many devices as you have...I tried having it autobalance, but only the devices I specified coordinates for showed up. The others may have been outside my field of view, didn't really look around too much. According to the nagiosexchange page for nagiosmap, "This is a Perl/Tk app desined to work with Nagios that allows you to graphically create 2-D coordinates for the statusmap CGI by dragging hosts around." Can you use this for 3d mapping? I really didnt check for such a program when I was mapping out my network...if this can do 3d, I wish I did! If not, I think the easiest way would be to do what I did, and just set up the network in repeating fashion so you don't have to figure out and change a bunch of really confusing coordinates. I will try to include a pic of part of my setup (i guess its more like 41 hosts than 60).
