An information processing apparatus monitors one or more apparatuses based on information on multiple items acquired from the apparatuses. Information on an item #3 is associated with information on items #1 and #2. The information processing apparatus examines the information on the item #3. In the case where no failure is detected in the examination of the information on the item #3, the information processing apparatus omits examination of the information on the items #1 and #2. On the other hand, in the case where a failure is detected in the examination of the information on the item #3, the information processing apparatus examines the information on each of the items #1 and #2.

Determination of items to examine for monitoring

An information collection device acquires information from a plurality of devices connected through a network. The information collection device includes: a first addition unit that adds, for each of the devices, an information collection duration required to collect information of the devices to a communication duration required to communicate with the devices; a second addition unit that adds a maximum duration among the durations by addition of the first addition unit to a predetermined time to obtain a first time; a subtraction unit that subtracts the information collection duration of each of the devices from the first time; a first setting unit that sets a time obtained by the subtraction unit as a second time that is when information collection starts at each of the devices; and an acquisition unit that acquires information obtained by the information collection that starts at the second time.

Information collection device, information collection program, and method

A configuration management system includes a plurality of MDRs that stores information about resources as configuration items, a FCMDB, a plurality of proxy apparatuses, and a proxy management apparatus, wherein the proxy management apparatus receives configuration items from the MDRs, reconciles the receives configuration items, selects a destination proxy apparatus such that the numbers of configuration items stored in the proxy apparatuses are substantially equal to each other, and sends the reconciled configuration items to the selected proxy apparatus, wherein the proxy apparatuses store configuration items sent from the proxy management apparatus, and wherein the FCMDB receives a query from a client, selects among the plurality of proxy apparatuses a proxy apparatus that stores a configuration item that is to serve as a query result, and receives the configuration item from the selected proxy apparatus.

When a problem occurs in a computer system, the following processing is performed. That is, a troubleshooting procedure that includes, at least, operation content and input request for system information, presented to an operator, and in which command to acquire system information related to the input request from the information source of the system information are assigned to the input request, is referenced. Furthermore, in accordance with the command, system information is collected from an information source where system information exists. Then, after those input request for system information have been removed from the troubleshooting procedure, the resultant troubleshooting procedure is presented to the operator. Thus, the workload of the operator in the troubleshooting operation can be significantly reduced, and the time until the operation is completed is shortened, making rapid troubleshooting possible.

An information management device for performing an information update process from a virtual integrated management device that manages a plurality of device configuration information management devices to the device configuration information management devices, comprises a meta information management unit and an update processing unit. The meta information management unit, which is used to store meta information, indicates from which device configuration information management devices managed information comes. The update processing unit is used to narrow down the device configuration information management devices having information. The information is the basis of information on an update process such as registration, update and deletion based on the meta information, and giving a request for the update process, such as registration, update and deletion only to the device configuration information management devices narrowed down.

A constraint condition DB storing a constraint condition that stipulates a structure of a decision tree is referenced, and a decision tree is generated from a case set where values of a plurality of attributes and a conclusion are associated with one another so that the structure of the decision tree, which is stipulated by the constraint condition, is satisfied. Accordingly, for example, even if a new case is added to the case set, a basic structure of the decision tree is succeeded by the constraint condition, thereby avoiding a situation where an operator needs to significantly modify the decision tree. Therefore, operations of modifying the decision tree by the operator can be reduced.

A supporting apparatus includes a configuration-information storage unit having stored therein dependencies among devices in association with a list of the devices. When information about a device where a failure has occurred is input, a dependency among devices including the faulty device is obtained from the configuration-information storage unit. Based on the obtained dependency among devices including the faulty device and information about the faulty device, learning data with the dependency and a cause of failure being associated with each other is created. Then, based on the created learning data, a solution procedure indicative of a procedure for specifying the cause of failure is generated by using, for example, algorithm ID3.
