1. A method for characterizing a health of a power supply in a computer system during operation of the computer system, the method comprising:
- generating a signature for the power supply based on measurements of a set of performance parameters for the power supply; and
characterizing the health of the power supply based on a comparison between the signature for the power supply and signatures for one or more other power supplies.

Abstract
Some embodiments of the present invention provide a system that controls a device that characterizes the health of a computer system power supply. During operation, a signature for the power supply is generated based on measurements of a set of performance parameters for the power supply. Then, the health of the power supply is characterized based on a comparison between the signature for the power supply and signatures for one or more other power supplies.
