  • Publication number: 20200394091
    Abstract: A failure analysis support system calculates a failure analysis period based on a metric performance value of a bottleneck candidate resource and a metric base value corresponding to the metric performance value, identifies a bottleneck candidate related resource related to the bottleneck candidate resource by referring to inter-resource relation information, calculates an evaluation value of the bottleneck candidate related resource based on a metric performance value of the bottleneck candidate related resource and a metric base value corresponding to the metric performance value, identifies a to-be-displayed bottleneck candidate related resource from the bottleneck candidate related resource based on the evaluation value, and displays a mutual relationship between display resources including a base point resource, a base point-related resource, the bottleneck candidate resource, and the to-be-displayed bottleneck candidate related resource, and a status of the display resources at each time point in the fa

  • Patent number: 8164324
    Abstract: A rotation sensor includes a detecting portion, a rotational state determining portion and a pulse generating portion. The detecting portion detects a rotation of a rotational member and outputs a detection signal. The rotational state determining portion determines a rotational state of the rotational member on the basis of the detection signal in a predetermined period. The pulse generating portion generates and outputs a first pulse and a second pulse, of which waveforms differ from each other, in response to a rotational direction of the rotational member after the predetermined period. The pulse generating portion further generates and outputs a third pulse regardless of the rotational state of the rotational member in the predetermined period.

  • Publication number: 20030187769
    Abstract: To reduce workloads given to a manager who manages computers and the like, a manager program for managing information processing apparatus is provided with a management apparatus. The manager program judges whether or not an information processing apparatus is operated within a use term based upon information of the use term of the information processing apparatus. If the manager program judges that the information processing apparatus is operated within the use term, the manager program registers a fact that the information processing apparatus corresponds to assets into a storage unit of the management apparatus, and judges whether or not the information processing apparatus is operated within the use term. If the manager program judges that the information processing apparatus is not operated within the use term, the process operation of the manager program is accomplished.
