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.

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
