HI Tianran, Alex, the power consumed at a given time is highly changing over time, but parameters like e.g. power consumption of a card at 50%, 75% and 100% of the load don't. I don't disagree with Alex when saying that this is not directly inventory, but it's strictly related to it and should probably be an augmentation of the device inventory.
