Power measurement - Energy usage vs Usage

[AndreasHammargr]

Im looking on the performance tab of a ESXi 4.1 server (Build 381591).

Looking under "Power", I have two metrics called "Energy usage" and "Usage" to choose from.

Which one of these is representing the actual power usage of the server, and what is the other one?

These differ with a factor of about 20 for me, so they are quite different.

"Usage" shows you the current power in use at the point in time.  "Energy usage" is a summation, so will show you energy use over a period of time.

I haven't really looked much in to these stats so I am not certain how accurate they are.

Are these definitions documented somewhere?
