Abstract: 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.

Abstract: 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.

Abstract: User data backup functions are realized through a computer, which is located on the management service provider corporation side and interfaces between a user side computer environment and a storage service side computer environment to support storage service. This computer selects storage devices which meet the user side conditions from a plurality of entirely or partially empty storage devices owned by the storage service side computer environment. The computer receives user data from the user side computer environment, divides the user data into records of a predetermined size and transmits the records to the storage service side computer environment so that the records are distributed and stored to the selected storage devices.

Abstract: 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.
