    摘要: Methods, systems, and articles of manufacture consistent with the present invention train a real-time health-monitor for a computer-based system while simultaneously monitoring the health of the system. A plurality of signals that each describe an operating condition of a subject data processing system are monitored in real-time. It is determined whether there is a problem with the subject data processing system by comparing at least one of the monitored signals to a corresponding at least one signal in a known signal dataset. The known signal dataset includes a signal value for at least one signal that describes an operating condition of one of a plurality of subject data processing systems. A new signal dataset having an entry for each monitored signal and a corresponding signal value is prepared simultaneously with monitoring the plurality of signals and determining whether there is a problem.

    摘要: One embodiment of the present invention provides a system that monitors a computer system using a plurality of physical sensors. The system operates by polling the plurality of physical sensors in a given sequence at a given rate, wherein each physical sensor monitors a specific physical parameter of the computer system. The system then provides a plurality of measurements from the plurality of physical sensors to a monitoring system. If a given physical sensor detects a parameter that is not within a pre-determined operating range, the system receives an interrupt from the given physical sensor. In response to receiving this interrupt, the system raises an alarm.

    摘要: One embodiment of the present invention provides a system that validates sensor operability in a computer system. During operation, the system perturbs the computer system with an excitation, wherein the excitation may be physical or software-based. The system then receives a number of responses to the excitation through sensors in the computer system, wherein each response is represented as a value of a variable which may vary with time. Next, the system compares the received responses with a set of reference responses gathered from properly functioning sensors in a reference computer system. The system then determines from the comparison whether the sensors in the computer system are operating properly.

    摘要: A method and system for monitoring an industrial process and a sensor. The method and system include generating a first and second signal characteristic of an industrial process variable. One of the signals can be an artificial signal generated by an auto regressive moving average technique. After obtaining two signals associated with one physical variable, a difference function is obtained by determining the arithmetic difference between the two pairs of signals over time. A frequency domain transformation is made of the difference function to obtain Fourier modes describing a composite function. A residual function is obtained by subtracting the composite function from the difference function and the residual function (free of nonwhite noise) is analyzed by a statistical probability ratio test.

    摘要: Some embodiments of the present invention provide a system that attenuates noise from a fan exhaust of a computer system. During operation, the system monitors the noise from the fan exhaust and calculates a frequency spectrum of the noise from the monitored noise. Next, the system generates an antiphase spectrum from the frequency spectrum and generates a flow of air which exhibits a property of the antiphase spectrum. Finally, the system directs the flow of air into the fan exhaust so that the noise is attenuated by a reduction of turbulence in the fan exhaust by the flow of air.
