Abstract: A load calculation program that causes a computer a process includes acquiring processor usage information including usage of a processor of an managed computer, which is a management object, and usage of the processor for each of a plurality of virtual machines generated by a hypervisor executed on the managed computer; acquiring data transmission information including a data transmission amount for each virtual network interface used by the plurality of virtual machines; detecting a first virtual network interface that performs data transmission without routing through the hypervisor among the plurality of virtual network interfaces, based on the processor usage information and the data transmission information; and calculating load information including processor usage for data transmission of each of the plurality of virtual machines, based on whether or not each of the virtual machines uses the first virtual network interface.

Abstract: An information processing apparatus calculates, at the time of moving a virtual machine which operates on a first physical machine, an amount of a first resource which the virtual machine can use on a second physical machine without sharing with another virtual machine. The information processing apparatus estimates response time of the virtual machine at the time of moving the virtual machine to the second physical machine on the basis of response time of the virtual machine at the time of the virtual machine operating on the first physical machine and the amount of the first resource. At this time the information processing apparatus uses different algorithms at the time of a resource used by the virtual machine being within the first resource and at the time of the virtual machine using a second resource which the virtual machine shares with another virtual machine.

Abstract: A non-transitory computer-readable storage medium storing therein a management-information acquiring program that causes a computer to execute a process includes acquiring queries to a target database for a management target service system, specifying a reference target table in the database based on names of target tables included in the queries and content of the queries, specifying a reporting target table on the basis of data of the reference target table, causing the database to execute an acquisition query to the reporting target table, and acquiring specific management information from the reporting target table.

Abstract: A program that performs a virtual machine move control predicts a resource shortage, predicted to occur for a predetermined time period, of a physical server that includes multiple virtual machines and that is included in a management server; specifies a virtual machine that eliminate the resource shortage by moving, at a time point at which the predicted resource shortage occurs, among the virtual machine included in the physical server, for which the resource shortage is predicted, to another physical server; and moves the specified virtual machine to the other physical server on the basis of the resource usage of the specified virtual machine for the predetermined time period and on the basis of a time point that is associated with the resource usage.

Abstract: A data management apparatus obtains first operation information about a specified operation from an information processing apparatus; specifies second operation information that matches a registered operation pattern from the first operation information, by utilizing operation pattern information that includes correspondence information between the specified operation and the registered operation pattern, the operation pattern information being stored in a first memory; obtains a second log from a first log of the information processing apparatus, the second log corresponds to time periods in which the specified operations that are not permitted by the registered operation pattern are done, the first log being stored in a second memory; and specifies a time period of a log extracted on the basis of a performance value indicated by the second log.
