摘要:
A network-configuration management apparatus manages a configuration of a network in which a plurality of network devices including a plurality of servers is connected. An upper-layer-specification receiving unit receives an upper layer specification from a user. A grouping unit groups the servers based on the received upper layer specification. A configuration display unit that displays the configuration of the network based on the grouping of the servers.

According to this invention, it is possible to display the overall configuration of a network and, at the same time, an important part of the network in detail according to the objective of monitoring so as to be able to grasp/monitor the important part of the network in detail, while globally grasping/monitoring the network configuration, for the purpose of an efficient monitoring operation on the network configuration. A network configuration management apparatus 100 for managing the configuration of a network 101 formed by connecting a plurality of network devices comprises a topology information acquiring section 11 for acquiring topology information on each of the network devices and a degree of importance determining section 12 for computationally determining the degree of importance of each of the network devices, using the topology information acquired by the topology information acquiring section 11. The apparatus 100 displays a network map on the basis of the computationally determined degrees of importance.
摘要:
The communication availability information between a plurality of transmitters and a plurality of destinations before the communication state between a transmitter and a destinations in a communication network changes from available to unavailable is compared, layer by layer from an upper layer toward a lower layer, with the communication availability information after change, and destinations in paths where the communication state has changed from available to unavailable are grouped. Thus, the communication network is divided into a plurality of affected ranges and an interface of a device located at the border between the affected ranges is deduced as a fault occurrence point.

Connections included in the topology of a lower-order layer of a plurality of layers are grouped according to device setting information of a plurality of devices composing a communication network with a communication function having a hierarchical structure composed of the plurality of layers, and an information reach range in a higher-order layer is generated. Then, the topology of the higher-order layer is generated based on the obtained information reach range.

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.
摘要:
Based on past failure sign appearance situations and past failure occurrence situations, failure occurrence probability which varies with a time elapse after failure sign appearance is calculated, and also, based on maintenance cost information of an operations management objective system, a short-term troubleshooting cost required for responding to a failure associated with the failure sign appeared in the system is calculated. Furthermore, based on the past failure sign appearance situations and the past failure occurrence situations, and also, the maintenance cost information and the failure occurrence probability, a short-term first preventive maintenance cost required for preventive maintenance of the failure associated with the failure sign, and also, the failure occurrence probability and a short-term second preventive maintenance cost for when preventive maintenance performance is postponed until next failure sign appearance, are calculated. Then, options in which the short-term first preventive maintenance cost, the short-term second preventive maintenance cost and the troubleshooting cost are associated with the failure occurrence probability, are prepared to be offered via an output device.
