By selecting, as a monitoring API, an API which does not involve modifying information when executing a request, from APIs called by an AP to be monitored, transmitting a pseudo-request to the monitoring API, and receiving a response to the request, a monitoring node for determining whether or not the monitoring API is operating normally is created and is included in the AP.

Application operation monitoring apparatus and application operation monitoring method

In a system where resources are used in a varying manner, when performances are monitored based on detected past behavior when the system was operating normally, if performance behavior is detected that is different, it is difficult to determine whether the detected performance behavior results from resources being used differently than when the system was operating normally. According to the present invention, monitoring accuracy is improved by determining whether performance behavior results from change in characteristics relating to the usage of the system by using means for measuring performances when the system is in operation and detecting a performance different from when the system was operating normally, means for measuring characteristics relating to the usage of the system and detecting whether the characteristics are different from when the system was operating normally, and means for comparing performance information with characteristic information relating to the usage of the system.

Management computer and method of managing computer to be managed

A management device managing a storage device having a plurality of logical storage areas accessed by a computer has a monitor module for determining whether a setting is made by which the computer uniformly accesses the plurality of logical storage areas, obtaining respective access counts of the plurality of logical storage areas when it is determined that the setting is made, and comparing the obtained plurality of access counts, thereby determining whether a logical storage area having a problem exists; an analysis module for obtaining, when the problem exists, configuration information of the storage device assigned to the logical storage area having the problem, and identifying a configuration in the storage device as a bottleneck on the basis of the obtained configuration information; a creation module for creating a countermeasure of changing an access route passing through the configuration as the identified bottleneck.

Management device and management method

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.

Network monitoring device, network monitoring method, and network monitoring program

A management server monitors even the occurrence of items, which are not targets of security policies, evaluates a change of the monitoring result, and implements specific output when necessary. Particularly, also regarding items which are considered to be non-targets of the security policies in management based on the security policies, the occurrence of such items is also monitored and the monitoring result is appropriately reported to an administrator so that the administrator can recognize a threat and takes necessary countermeasure at appropriate timing.

A sender of a message can transmit a message to an unspecified user merely by specifying a condition of space without specifying a recipient of the message, using an information processing terminal transmitting a message not with a user address to specify a user but with an area address (a condition of space) to specify an area within an electric wave reachable range of a radio base station; and a server converting the area address to a user address which specifies a PHS terminal currently located in the area represented by said area address and transmitting the message with a converted address to a switching equipment.

In a storage session management system in a storage area network, the session information blocks periodically collected from the storage devices in the network are grouped based on the information indicating the relation between sessions. That is, since a storage session management server in the management system integrally manages constitution information and operation information, when there is a possibility that circumstances such as a failure and the deterioration of performance occur in information devices, a failure notification module displays such circumstances and makes notification of them to a minimum necessary range that is consolidated by a session consolidation module, thereby a storage session can be managed without applying loads on the respective information devices and the network.

In a system which manages path information and status of network with respect to a path being used for access to a storage apparatus and has a redundant path, when a fault occurs in the network, whether or not the path can be recovered by rerouting in network apparatuses is discriminated, thereby performing proper path switching. Construction information and the path information of the network are managed as information of the path which is being used for a storage access by a management server. Further, when the access path is made redundant, the management server obtains fault information in the network and information showing whether or not the path is being reconstructed from the network apparatuses, thereby discriminating the necessity of the path switching. If the path switching is necessary, the management server notifies a host computer and the storage apparatus of it and each apparatus executes a switching process.

The present invention decreases the burden of operation required for specifying the continuity status and the cause of failure of a network storage device. A host computer accepts the specification of the device identifier, that is an identifier of the network storage device in the host protocol which positions in a higher hierarchy than the network communication protocol, and a volume identifier, that is an identifier of the volume. Then based on the specified device identifier, the host computer specifies the network identifier, that is an identifier of the network storage device in the network communication protocol. And continuity is confirmed in the network communication protocol in which the specified network identifier is the destination. Also continuity is confirmed in the host protocol in which the device identifier is the destination. And the volume specified by the volume identifier is accessed.

In order to remove security vulnerability in an IP-SAN and eliminate unauthorized access by spoofing, firewalls are installed in valid user servers and storage devices, and a distributed firewall manager for managing the firewalls integrally is provided in the IP-SAN. The distributed firewall manager obtains discovery domain information from an iSNS server, determines nodes registered in the iSNS server as the nodes of valid users, and autocreates a security policy according to sets consisting of an iSCSI name and portal information. This security policy is distributed to all of the firewalls as a common policy, whereupon access control is executed to deny TCP connection requests from unauthorized access sources.
