  • Patent number: 8830850
    Abstract: Information on a communication relation or communication path to be monitored is automatically generated to reduce load of a user. A path information generation part receives a destination IP address designated by a user, through an input receiving part. When the input of the destination IP address is received, the path information generation part uses configuration information tables, each of which stores configuration information of a device on a network, to identify IP addresses of networks each having a plurality of terminals, as branch IP addresses. The path information generation part uses the configuration information tables and transfer destination information tables each storing a routing table of a router, to identify the connection order of routers between the designated destination IP address and the identified branch IP addresses, to generate path information.

  • Patent number: 8671186
    Abstract: The present invention makes it possible to analyze a problem spanning multiple domains. A management apparatus stores an analysis rule. The analysis rule defines a relationship between a causal event, which constitutes a cause of a problem, and multiple relevant events, which denote problems created by the causal event. A first management apparatus acquires a relevant event related to a prescribed node apparatus, which is not under management of the first management apparatus, from a second management apparatus, which manages the prescribed node apparatus. The first management apparatus analyzes a problem by applying the relevant event acquired from the second management apparatus and another relevant event related to a node apparatus under the management of the first management apparatus to the analysis rule.

  • Patent number: 8656406
    Abstract: In a system including a load balancer to select a virtual server to which a request is to be transferred, the load balancer includes a function to monitor resource use states of physical and virtual servers and a function to predict a packet loss occurring in a virtual switch. The request count of requests processible by each virtual server is calculated based on the resource amount available for the virtual server and a packet loss rate of the virtual switch, to thereby select a virtual server capable of processing a larger number of requests.

  • Patent number: 8369227
    Abstract: Provided is a management system for managing a plurality of management target information processing apparatuses including a plurality of network apparatuses and a computer. This management system determines the reachability of a route network apparatus as a network apparatus on a communication between the system and the computer, and calculates a certainty factor concerning the certainty on whether a prescribed network apparatus contained in a route network apparatus based on the reachability is the cause of unreachability from the management system to the computer. The management system subsequently displays information showing that communication from the management system to the computer is unreachable, and the certainty factor as the certainty that the prescribed route network apparatus is the cause of unreachability.
