  • Publication number: 20210158248
    Abstract: A computer system includes a business system operating services each providing a function corresponding to a request. the computer system comprises: a controller generating a schedule for changing an allocation amount of a resource of the business system for a service; and an allocation change unit changing the allocation amount of the resource for the service based on the schedule. The controller calculates in a case of detecting reception of a request for starting processing, a reception count of the detected request; identifies related services; calculate a predicted value of an index indicating a load of each of the related services based on the reception count of the request; determines whether it is necessary to change the allocation amount of the resource for the each of the related services; and generates the schedule of a determined related service.

  • Patent number: 9881056
    Abstract: A monitor system transmits a request requesting event occurrence information to multiple node apparatuses, detects occurrence of an event on the basis of event occurrence information included in a response, calculates an index value of each of conclusions of multiple rules indicating corresponding relationship between one or more condition events and a conclusion, and generates, at a predetermined time point, a snapshot indicating an index value at that time point. When the monitor system receives a first response in reply to a first request, the monitor system updates the index value indicated by the snapshot generated in a period from a transmission date/time of the first request to a reception date/time of the first response, on the basis of the first response.

  • Patent number: 8935373
    Abstract: A system management apparatus for managing a computer system receives plug-in distribution data from a plug-in distribution apparatus. The plug-in distribution data comprises plug-in definition information and template definition information. The system management apparatus uses the plug-in definition information to acquire information from the management target apparatus, and determines whether or not to issue an alert based on the template definition information. The distribution of the plug-in and the template at the same time means that the user can avoid confusion regarding the threshold setting.

  • Patent number: 8799600
    Abstract: The present invention achieves data relocation in accordance with a user's policies, in an environment where a plurality of storage devices coexist. The volumes belonging to storage devices A-D are managed virtually integrally. A host recognizes a plurality of storage devices A-D as a single virtual storage device. The user is able to group arbitrarily each volume belonging to the storage system, as a plurality of storage layers 1-3. For example, storage layer 1 can be defined as a high-reliability layer, storage layer 2, as a low-cost layer, and storage layer 3, as an archive layer. Each storage layer is constituted by a group of volumes corresponding to respective policies (high reliability, low cost, archiving). The user designates volumes V1 and V2 to be moved, in group units, and indicates a storage layer forming a movement destination, whereby the data is relocated.
