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.

An analysis apparatus compares first code describing a plurality of first components with second code describing a plurality of second components, to extract difference components. The analysis apparatus sends a plurality of requests to an execution apparatus on which the plurality of second components are deployed, obtains first log information indicating the execution state of each difference component, and specifies relevant requests related to the execution of the difference components. The analysis apparatus sends the specified relevant requests to the execution apparatus and obtains second log information indicating the execution state of each of the plurality of second components. The analysis apparatus generates path information about second components executed in response to each relevant request among the plurality of second components, on the basis of the second log information.

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.
