Item values associated with an execution state of a program executed on a computer are collected in detail while suppressing the computer load. When reducing the interval for collecting values of one item to be monitored, the interval for collecting values of items other than that item is increased. If the computer load is increased, an interval of at least one item is increased. Moreover, there is provided an upper limit for the number of items whose intervals can be reduced simultaneously. Moreover, when varying the interval of the item according to the values of the respective items, the interval variation range is varied according to the item state and the computer load.

Method and program for monitoring execution state of program

A management computer includes a memory storing toplogical information including identifiers of ports of computers, storage apparatuses, and switches. The management computer includes a processor, which is configured to: collect a plurality of performance information of the ports, and a plurality of access times from computer ports to the storage apparatuses; evaluate that a certain access time among the plurality of access times exceeds a predetermined allowable range; search a first access path to which the certain access time corresponds; search at least one second access path starting from a first computer port on the first access path; and search performance information of certain ports which are on the at least one second access path in order to display the searched performance information.

Storage network system, managing apparatus, managing method and program

A storage network system includes computers, storage systems, connection devices that control connection relations between the computers and the storage system, and a managing device that manages the computers, the storage system and the connection devices. The managing device includes a control section that specifies connection ports of the computers, the storage system and the connection devices that compose the storage network system. Further, the control device of the managing device displays on a display section a data traffic amount at each of the connection ports for each connection path from the computer to the storage system.

A method and system of examining resource reliability in which a data acquisition section collects a utilization performance record of a resource previously recorded in a utilization performance record storage and data on the resource stored in a Web server and stores them, and a reliability judge section judges the reliability of the resource based on the data stored in the data acquisition section. The resource with high reliability is offered based on the results of the judgment in response to a request.

To provide a file transfer method and system capable of making backups in a unified manner at backup sites and MSP (Management Service Provider) operating under an around-the-clock system with high reliability equipment. When data to be transferred such as backup is transferred between SAN (Storage Area Network) storing units to back up the data stored in the SAN, a data transfer instruction is sent to the transfer source and transfer destination of the data transfer via a network which is different from the SAN.

File transfer method and system

In one embodiment of the invention, a disk storage accessing system for enabling a plurality of computers to share and access a plurality of disk storages comprises a plurality of computers that refer to the disk storages. Each of the computers includes a counting module for counting a frequency of accesses to each of the disk storages, and a module for receiving an access path change command to change access paths for the computer to access a different disk storage according to the command. The system further comprises an instructing module for collecting and totaling a frequency of accesses to each disk storage, and for instructing the receiving module of a computer that accesses the copy source disk storage after receiving a report of copy completion, to change access paths so as to access a target disk storage instead of the copy source disk storage.

Disk storage accessing system and method for changing access path to storage devices

A backup or restore schedule is determined in an efficient manner. A backup definition creating unit in a management server reads a start time of a service managed by a job schedule unit, and sets a backup start time in a time zone in which the service is not executed.
