I know many of you have been waiting on this so I figured I would report it is available. You can find the official vSphere License Advisor on here. I know many have used Alan’s script, and some couldn’t use it because it didn’t support VI3. The vSphere License Advisor will work in environments with Virtual Infrastructure 3.5, vSphere 4.0 and vSphere 4.1 so pick it up and run it.
