Abstract
One embodiment of the present invention provides a system that facilitates using a multi-variate pattern-recognition technique to trigger software rejuvenation for a computer system. The system operates by periodically measuring values of a target set of performance parameters associated with the computer system while the computer system is operating. The system then predicts values for the target set of performance parameters based upon previously determined correlations between performance parameters in the target set of performance parameters. If the predicted values deviate beyond a predetermined threshold from the measured values, thereby indicating that software aging is likely to have occurred, the system schedules a software rejuvenation operation for the computer system.
