Abstract: A system management apparatus for managing a network system, the system management apparatus includes a processor configured to perform specifying of a first communication path including the L3 relay apparatus between a first pair of information processing apparatuses included in the network system and a second communication path not including any L3 relay apparatus between a second pair of information processing apparatuses included in the network system, store management information in the memory, the management information including information of the first communication path and the second communication path in association with information of the first pair of information processing apparatuses and the second pair of information processing apparatuses, and when a failure occurs in the network system, perform a detection of communication between a third pair of information processing apparatuses affected by the failure.

Abstract: An information processing apparatus includes a memory and a processor coupled to the memory. The memory is configured to store device connection information indicating a connection destination device coupled to a first device among a plurality of devices included in a communication network. The processor is configured to: search physical address learning information of the connection destination device in preference to physical address learning information of search target devices other than the connection destination device on basis of the device connection information. The physical address learning information of a specific device includes physical addresses learned for every port of the specific device. The search target devices are the plurality of devices other than the first device. The processor is configured to: obtain a connection destination port coupled to a first port of the first device on basis of a result of the search.

Abstract: A non-transitory, computer-readable recording medium stores a monitoring program that causes a computer to execute a process that includes acquiring from a server among a group of servers that are migration candidates for a monitored virtual machine, identification information of a virtual machine operating on the server; identifying classification of the virtual machine that corresponds to the acquired identification information, by referring to a storage unit that correlates and stores identification information of the monitored virtual machine and classification of the monitored virtual machine; and correlating and outputting the identified classification of the virtual machine, the identification information of the virtual machine, and identification information of the server.

Abstract: The corresponding between resources of two different displaying category can be easily grasped by: inputting an assignment of a focused resource; specifying one or more relative resources which are related to the focused resource and which belong to the second displaying category by referring to resource information recording a plurality of resources belonging to a first displaying category and a plurality of resources belonging to a second displaying category of the information processing system in association with each other, using the focused resource; and emphasizing the specified relative resources in a first resource map, the first resource map being displayed on a displaying device and coupling the plurality of resources belonging to the second displaying category.

Abstract: A management device includes a storage unit and a processor. The processor is configured to store, when configuration information is updated by one client of a plurality of clients, the updated configuration information, generation information on a generation of the updated configuration information, and identification information of the one client in association with one another in the storage unit. The processor is configured to generate, when restoration to a first generation is requested by a first client, new configuration information with reference to information stored in the storage unit. The new configuration information does not include first contents of first updates made by the first client in second generations later than the first generation and includes second contents of second updates made in the second generations by second clients. The processor is configured to perform a configuration of a network device using the new configuration information.

Abstract: A network managing apparatus detects a router capable of using Telnet from among nodes in a network and causes that router to send a broadcast ping to other nodes. Each node in the network returns a ping reply to the router. The ping and the ping reply pass through a switch before arriving at their destinations. When the ping and the ping reply pass thorough the switch, the switch extracts MAC addresses of sender nodes and store them in its MAC address table. Thus, accurate topology of the network can be obtained from the MAC address table of the switch.
