A failure reproducing apparatus according to the present invention includes a log analyzing unit that determines processes that have caused a failure when the failure has occurred in a server system, a target-value calculating unit that calculates a target value on the basis of execution time of each process, and a time-lag calculating unit that calculates a time lag. An execution control unit adjusts timing of outputting an execution command of each process to the server system on the basis of the target value and the time lag and executes a reproduction test.
