Abstract: An apparatus monitors a communication system including at least one communication device. The monitoring apparatus includes a memory, a processor. A second virtual system is generated by changing a first virtual system determined according to a combination of an arrangement of a plurality of virtual machines arranged in the at least one communication device, and a communication path between the plurality of virtual machines. The memory stores system information that represents an arrangement and a communication path of virtual machines used in the second virtual system. The processor receives the fault information that reports an occurrence of a fault. The processor identifies the fault information as being generated in the virtual machine within the first virtual system when a specified fault detected in a case where the fault information is transmitted from any of the virtual machines within the second virtual system represented by the system information is not detected.

Abstract: A control device includes a collecting unit that collects load information representing load at execution of an application from an information processing device which executes the application, a determining unit that determines whether or not the load represented in the load information collected by the collecting unit exceeds a predetermined threshold value, a deciding unit that obtains an increase/decrease amount of the load at the execution of the application using the load information collected by the collecting unit and load information collected in past by the collecting unit, and decides an amount of resource to be allocated at the execution of the application based on the obtained increase/decrease amount, when the determining unit determines that the load exceeds the predetermined threshold value, and an allocation unit that allocates the amount of resource decided by the deciding unit to the application.

Abstract: A disclosed bus system includes multiple server agents corresponding one-to-one with server applications; and multiple user agents corresponding one-to-one with user applications. Each server agent includes a first server-agent communication unit for communicating with the corresponding server application; a server-agent determination unit for determining as communication targets one or more selected from the user agents and the other server agents; and a second server-agent communication unit for communicating with the communication targets determined by the server-agent determination unit. Each user agent includes a first user-agent communication unit for communicating with the corresponding user application; a user-agent determination unit for determining as communication targets one or more selected from the server agents and the other user agents; and a second user-agent communication unit for communicating with the communication targets determined by the user-agent determination unit.

Abstract: According an aspect of the embodiment, there is provided a method for managing management target devices each connected to a computer network and managed by one of a plurality of management servers. A management server list storing IP addresses of the plurality of management servers is provided. A hop count defined as the number of hops, in the computer network, from the management target device to the each of the plurality of management servers is obtained and a management server having the smallest hop count among the plurality of management servers is selected as an optimum management server. Then, the management target device is managed under the control of the selected optimum management server.

Abstract: An operation management system for managing operation of a network-connected apparatuses includes an apparatus operation managing agent and a management server. The apparatus operation managing agent is provided in the network-connected apparatus to be managed, and independently manages an operational state of the network-connected apparatus, and autonomously sends, through a network, a management result of the network-connected apparatus managed. The management server receives the management result through the predetermined interface, and manages the received management result so as to manage the network-connected apparatus to be managed.
