Initially, I like to have NPM discover EVERYTHING. When I'm trying to wrap my brain around a new infrastructure, I need to know what's out there. Servers, switches, storage, hypervisors, even desktops...

Good stuff. For me, I actually find the "out of the box" defaults way too overbearing and tone it down even before deployment. I can, however, see your point in letting it all go to get a sense of...
