A monitoring system is configured to perform a cause analysis of an event which occurs in any of a plurality of node apparatuses. The monitoring system is configured to store a plurality of rules indicating a correspondence relationship between one or more condition events regarding any of the plurality of node apparatuses, and a conclusion. The monitoring system is configured to specify the first conclusion associated with the detected condition event based on the rule, and perform a detection possibility judgment on whether the monitoring system can detect the condition event or not, for each of one or more condition events out of a plurality of condition events, and calculate the first index value indicating the certainty of the first conclusion being the cause, based on the existence of detection of one or more condition events associated with the first conclusion and the result of the detection possibility judgment.

Monitoring system and monitoring program with detection probability judgment for condition event

The management system identifies a first event regarding a first node apparatus estimated to occur when a first maintenance work is performed on a first node apparatus based on maintenance work information that indicates a correspondence relationship between each maintenance work of one or more maintenance works for any of the plurality of node apparatuses and an event regarding a node apparatus to be the target of each maintenance work, which is estimated to occur when the maintenance work is performed. The management system identifies the range of effect and phenomenon of the case where the first maintenance work is performed on the first node apparatus, by performing simulation based on one or more rules indicating a correspondence relationship between one or more conditional events and a causal event and displays the identified range of effect and phenomenon.

Management method and management system

A management apparatus stores attribute/protocol management information denoting each attribute/protocol relationship. The management apparatus, for each of multiple addresses prior to inputting the credential used to detect the communication apparatus, (A) issues a query that specifies an address, (B) upon receiving a response to this query from the communication apparatus at the address specified in this query, writes, to a storage resource, query result information denoting the corresponding relationship between the address specified in this query and the communication apparatus attribute acquired based on the response, (C) identifies the management protocol corresponding to the communication apparatus attribute denoted by the query result information from the attribute/protocol management information, and (D) decides the optimum management protocol for the address based on the identified management protocol.

Method and management apparatus for detecting communication apparatus coupled to communication network

An embodiment of this invention is a system that recommends a change of management jobs for a plurality of apparatuses separated into a plurality of groups. This system selects groups one by one from the plurality of groups. It determines a similarity degree among the management jobs set to the plurality of groups after changing the current management job to a different management job. It determines at least either one of a management cost of the current management job and a management cost of the different management job. It determines a recommendation degree of the change of the management job using the determined similarity degree and the determined management cost. It presents a pair for a recommended change of management jobs in accordance with the determined recommendation degrees.

Graphical user interface for a display screen

A method for storage management is provided which displays the materials on which it is determined which of the thin provisioning volume or the logical unit (LU) is to be used for storage promotion. The method is executed in a computer system having one or more host computers, one or more storage subsystems, and a management computer. The storage subsystem includes a physical disk and a disk controller. The disk controller provides the host computer with the thin provisioning volume. The management computer obtains the allocated capacity from the disk controller and the host-recognized capacity from the host computer. By subtracting the obtained allocated capacity from the host-recognized capacity, the management computer calculates an improved capacity. By dividing the calculated improved capacity by the obtained host-recognized capacity, the management computer calculates an improvement ratio and displays the calculated improvement ratio.

Method and a computer for storage area management

A user operates an input device to set information necessary for reserving a volume and a port while looking at a screen for reservation management displayed on a display device Next, a storage management program retrieves reservable volumes and ports using a volume retrieval subprogram of a policy basis. At this point, when a policy concerning performance is inputted, the storage management program inquires of a performance analysis program of a storage performance management server whether the performance is satisfied. When the volume and the port are found, the storage management program stores reservation information in a reservation management DB using a reservation subprogram. When the volume and the port are not found, the storage management program judges whether an alternative volume for the reserved volume is present using a volume adjustment subprogram.

Method and system for managing storage reservation

A Business to Business electronic commerce (BtoB) system includes a message exchanging section, a task processing section and that conforms to BtoB standard specifications, and a difference processing section is added. For an outgoing business document, the difference processing section creates difference information between a past transaction and a new transaction within the range of the BtoB standard message format and sends the message to a business counterpart. For an incoming business document, the difference processing section restores a new transaction based on a past transaction and difference information.
