Read only agent / collector

I would also like to add that if we're going to need a full blown collector, that I think even a "nano" sized collector is overly large for single device monitoring.  I'd ideally like to see something in the 512MB or less memory wise and 1 vCPU.  if all its doing is monitoring locally, I would like to assume it doesn't need a ton of resources.  Of course that a big assumption.  Admittedly, 512MB is an arbitrary number I made up, but something less than 2GB for sure.
