Abstract: A method includes: determining, based on an elapsed time, a priority for each of groups obtained by clustering a plurality of pieces of response information based on similarity between the pieces of response information, each response information indicating a response to an event that has occurred, the elapsed time being measured from a time period in which the event recorded in each response information of each group occurred most often; calculating credibility for each response information, based on a number of times specifications of a system relating to the event have been changed after the response, and an elapsed time from date and time when the response recorded in the pieces of response information has been made; and controlling a presentation mode upon presenting the plurality of pieces of response information, based on the priority calculated for each group and the credibility calculated for each response information.

Abstract: An analysis support method includes: searching for a second physical machine that has a configuration similar to a first physical machine on which a first virtual machine to be analyzed is executed, the second physical machine having configurations similar to the first physical machine before and after a change of a state of a virtual machine executed on the second physical machine; and searching for a second virtual machine that is executed on the second physical machine and similar to the first virtual machine before and after the change of the state of the virtual machine.

Abstract: Processing request information of a processing request for a first computer by a second computer is acquired, first operation information and second operation information that relate to operations of the first computer and the second computer are acquired, respectively; and a type of the processing request is determined based on processing result information, the processing request information, the first operation information, and the second operation information. The processing result information associates a processing history of the first computer according to the processing request included in the processing request information for the first computer with the second operation information that relates to the processing request by the second computer making the processing request. Accordingly, the type of the processing request can be appropriately determined.

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.
