PROBLEM TO BE SOLVED : To provide a technique capable of controlling a trace log output according to a rare state which can not be previously predicted by a programmer or a load state of a computer system.SOLUTION : A trace logging method for outputting a trace log for the execution of a program comprises a step for measuring execution information indicating the dynamic information of a program for the execution of the program and storing the execution information in a storage device and a step for reading out a measurement value which is the execution information stored in the storage device, calculating an evaluation value for evaluating the measurement value, and when the calculated evaluation value satisfies a threshold condition specified by a policy definition table, outputting the trace log to the storage device.COPYRIGHT : (C)2008, JPO&INPIT
