Thanks for the response. We really started custom building our own tool, in house, to do exactly what we wanted. We manage about 150 physical servers, so we can't benefit from the underlying hypervisor info that some VM platforms provide. We have been writing our own, and subsequently feel like we could offer this at a very affordable price. We hadn't seen Scout, mostly because we just dove right into making our own tool. We're now doing some research and are finding that we're right on track in terms of being in line with functionality that others provide - like Scout. We're not tied to Ruby, though. I don't even know if our Linux servers come with Ruby - never used it. Admittedly, ours is a little less mature, which is not a bad thing since we are so new, but we're going to continue following our gut on this and just make it as useful of a tool as possible.
