Interpreting ESXTOP Statistics:
VMware has just released a very nice paper of Interpreting ESXTOP Statistics. ESXTOP is used from the console OS and if often overlooked as a extremely valuable tool. There was an excellent session on this topic at VMworld 2008 that really needed to be two hours in length..but this document looks very nice...so get it now!
