Abstract: A processor calculates a correlation between a first data item and a second data item, based on values of the first data item in a first log and values of the second data item in a second log, and determines an influence direction by comparing values of a first chronological item with values of a second chronological item. The processor collects third and fourth logs respectively generated later than the first and second logs. The processor determines whether the correlation holds with respect to values of the first data item in the third log and values of the second data item in the fourth log, and outputs an anomaly report, when the correlation does not hold, to indicate which of the first and second data items is a cause data item (i.e., the source of an anomaly), based on the influence direction.

This configuration makes it possible to specify an exact problem point.

Abstract: A determination unit determines a precondition indicating an expected state of a system that is to execute processing corresponding to an operation, and a postcondition indicating an expected state of the system that has executed the processing corresponding to the operation, based on a work log of previously-performed work. An association unit associates each of a plurality of operations with an operation whose precondition matches a postcondition of the each of the plurality of operations. A search unit searches for a path that starts from an operation whose precondition matches an initial condition satisfied by an operation object system, traces an associated operation, and reaches an operation whose postcondition matches a target condition indicating a target state of the operation object system after work. A generation unit generates an operation procedure in which operations on the path found by the search are arranged in order.

Abstract: A test control device stores therein, for each user who revises a system that includes a plurality of components, a use configuration table in which the type of the components that are used in revision is associated with the connection relation between the components that are used in the revision. When the test control device receives a request from a terminal device, the test control device specifies, on the basis of the use configuration table associated with the user of the terminal device, the type of the component that serves as the transfer destination of the request. When the server device associated with the specified type is running, the test control device transfers the request to the server device and transfers, when the server device has not been started up, the request to the started up server device after starting up the subject server device.

Abstract: Common parameters in common between a plurality of request logs are extracted from parameters in the plurality of request logs. The plurality of request logs is obtained when a request is executed by a process that uses a plurality of components. A common parameter different from a common parameter extracted for another process among the extracted common parameters is determined as an identification parameter that identifies the process. This allows accurately categorizing the process based on a log to be obtained when the process is executed.
