Method and apparatus for monitoring the health of a computer system
First Claim
Patent Images
1. A method for monitoring the health of a computer system, comprising:
- receiving a variance of a time series for a monitored telemetry variable within the computer system,calculating a residual function of the variance of the time series for the monitored telemetry variable;
calculating a first-difference function of the variance of the time series from the residual function;
determining whether the first-difference function indicates that the computer system is at the onset of degradation; and
if so, performing a remedial action.

Abstract
A system that monitors the health of a computer system is presented. During operation, the system receives a first-difference function for the variance of a time series for a monitored telemetry variable within the computer system. The system then determines whether the first-difference function indicates that the computer system is at the onset of degradation. If so, the system performs a remedial action.

19. An apparatus that monitors the health of a computer system, comprising:
-
a receiving mechanism configured to receive a variance of a time series for a monitored telemetry variable within the computer system, a residual-calculation mechanism configured to calculate a residual function of the variance of the time series for the monitored telemetry variable; a difference-calculation mechanism configured to calculate a first-difference function of the variance of the time series from the residual function; a degradation-detection mechanism configured to determine whether the first-difference function indicates that the computer system is at the onset of degradation; and a remedial-action mechanism, wherein if the degradation-detection mechanism determines that the computer system is at the onset of degradation, the remedial-action mechanism is configured to perform a remedial action.
