  • Patent number: 9894291
    Abstract: A moving image acquiring part acquires a moving image. A still image accumulating part stores still images. An image processing part calculates gains obtained by previously storing based on the costs of extraction of still images from a moving image, and extracts some still images with higher gains from among the still images composing the moving image and stores into the still image accumulating part. A request processing part retrieves a still image requested by a request source from the still image accumulating part and transmits to the request source and, when the still image requested by the request source is not stored in the still image accumulating part, extracts the still image requested by the request source from the moving image acquired by the moving image acquiring part and transmits to the request source.

  • Patent number: 9235492
    Abstract: A load information acquiring unit (230) sets load information based on the history that is acquired by a process history acquiring unit (220). A test period determining unit (240) sets a test period based on the load information. The test period is a period during which a test policy can be used. The test policy is a policy for a test out of control policies used by an information processing system (100). A system control unit (260) measures performance capability of the information processing system (100) under the test policy as a test result by testing the test policy under a production environment of the information processing system (100) by using the test policy instead of a practical policy that is actually used in the test period. A policy changing unit (270) changes the practical policy based on the test policy in a range in which the test result satisfies a reference.

  • Patent number: 8756093
    Abstract: A rejection determination is made taking into consideration of an agreed service level for a combine workflow executed on a combine workflow system wherein a plurality of business application are collaborated with one another for business collaborations. A state is expressed which will appear when the combined workflow is hypothetically rejected, based on the progress thereof. A processing operation of the combined workflow is predicted based on the expressed state, taking into consideration the influence exerted on the plurality business application systems and the plurality of workflow systems in respect of response performance. A processing operation, which is the result of the prediction, and historical information of event information from the event information recording means are retrieved, and an evaluation value is calculated based on the result of the statistical processing of the historical information.

  • Publication number: 20100013634
    Abstract: Disclosed is a distributed systems monitoring system comprising information monitoring units for acquiring monitoring information from monitoring targets, and a monitoring information collecting and integrating unit for integrating the monitoring information acquired from the information monitoring units and for presenting the integrated monitoring information to a user. Upon receipt of monitoring information from the monitoring target, the information monitoring unit determines whether or not the monitoring information has a high degree of urgency. If the information has a high degree of urgency, then the monitoring information is notified to the monitoring information collecting and integrating unit. Otherwise, the monitoring information is stored in a monitoring information holding section, and is transmitted each time a monitoring information request is received from the monitoring information collecting and integrating unit.
