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: 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 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.
