  • Patent number: 8583789
    Abstract: An object of the present invention is to create information for use in problem analysis only for a required event in a case where an event denoting a change in the configuration of a computer system has been detected. A management apparatus detects a configuration change of the computer system as an event and records this event in an event management table T30. The management apparatus holds an event propagation model for analyzing a problem, and records an event corresponding to the event propagation model in target event management information T34. The management apparatus executes a problem analysis process in a case where a detected event is registered in the target event management information.

  • Patent number: 8554906
    Abstract: To enable the setting of a suitable threshold for a component of each of apparatuses configuring a system. By using management software, a threshold for monitoring the performance of an apparatus to be monitored is set beforehand. When an acquired performance value exceeds the threshold, the acquired performance value is detected as a performance fault event. Further, the management software has a correlation analysis rule representing a causal relationship between the performance fault events in the managed apparatus. When detecting an event, the management software performs fault cause analysis processing to specify a fault cause apparatus and an apparatus (affected apparatus) affected by the fault from a plurality of received events.

  • Publication number: 20130226494
    Abstract: A digital filter for a digital weigher reduces a calculation time in an adapted filter while maintaining weighing accuracy, a digital weigher includes the filter for the weigher, and a wave filtering process method uses the digital filter for the digital weigher. A fixation section of a FIR filter removes an oscillating component in a predetermined frequency range, from a digital weighing signal. A determination device determines whether an amplitude of an oscillating component contained in a digital weighing signal derived by performing a wave filtering process falls within a predetermined damping range. A control device changes a frequency range of an oscillating component to be removed by an adaptive section of the filter based on a result of the determination. The adaptive section of the filter performs the wave filtering process with respect to the oscillating component in the frequency range changed by the control device.

  • Patent number: 8429455
    Abstract: There is provided a failure analysis function capable of reducing the time required to resolve a failure in a piece of equipment to be monitored. When the failure analysis function senses that the status of a piece of equipment which had been abnormal has returned to normal, it displays, of failure analysis results, one based on an equipment abnormality which has been resolved in a GUI separately from the other analysis results. If a failure analysis result is derived based on a plurality of failure events, the failure analysis function displays the failure analysis result in the GUI separately from the other failure analysis results when all of the failure events are confirmed to be resolved (see FIG. 16).
