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;
communicating the signature to a doctor server;
communicating other signatures for one or more other power supplies to the doctor server; and
characterizing the health of the power supply based on a comparison between the signature for the power supply and the other signatures for the one or more other power supplies, wherein characterizing the health of the power supply comprises characterizing the health of the power supply based on signature distances between the signature for the power supply and the other signatures for the 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.
