Abstract: 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.

Abstract: 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.

Abstract: A response time of an access to an application is monitored, and, when a trouble may occur, an alert is given to an administrator to reduce a workload on the administrator. A response time of the application is measured, a request in which the response time exceeds a reference value is extracted, and exceeding requests are aggregated in units of predetermined time widths. An interval between adjacent time bands in which the exceeding requests are present is calculated to determine a periodical tendency of occurrence of exceeding. An alert having a level depending on the tendency is output.

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.

Abstract: With a plurality of computer apparatuses connected to a network, operation log information, including an operation type and an output destination of a file, and acquisition source information indicating an acquisition source of the file are recorded based on a user's input/output operation; the acquisition source information is managed by relating it with an access authority over the acquisition source of the file; when the operation log information for the user's output operation exists in the operation log information, a range of the access authority over the acquisition source of an output target file, which is a target of the user's output operation, and an addressee user who can access an output destination of the output target file are specified; whether or not the addressee user belongs to the range of the access authority over the acquisition source of the output target file is judged; and if a negative judgment result is obtained, risk information indicating that the user's output operation is an out

Abstract: 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.

Abstract: In a computer system that comprises multiple target computers and an analysis computer, one or more first target computers, in which a predetermined application has been installed and invoked, send a log comprising information of multiple configuration changes that have been made prior to invoking the predetermined application to the analysis computer, and the analysis computer receives the log and computes, for each type of configuration change and based on the log, an invocation failure rate which is a percentage at which the invocation of the predetermined application fails subsequent to the configuration change. Then, a second target computer receives, from the analysis computer, first information comprising an invocation failure rate for each type of configuration change related to the predetermined application, and based on the invocation failure rate, displays the type of configuration change that is the cause of the failure of the predetermined application invocation.

Abstract: 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.

Abstract: 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.

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 of a network monitoring device receives a destination IP address designated by a user as an object of monitoring. When the input of the destination IP address is received, the path information generation part uses configuration information tables, which store configuration information of a device on a network being monitoring, to identify IP addresses of networks to which a plurality of terminals belong, as branch IP addresses. Further, the path information generation part uses the configuration information tables and transfer destination information tables which store a routing table of a router on the network, in order to identify the connection order of routers between the designated destination IP address and the identified branch IP addresses, to generate path information.
