Zusammenfassung:PURPOSE: To provide a trace collection method and a computer system which can keep the continuity of the trace data despite high load of a CPU of an execution program. CONSTITUTION: A trace collection program 105 is called out of an optional module of an execution program 103 during execution of the program 103 and a load monitor program 104. Then the program 105 refers to a trace importance number 114 that is updated in steps and according to the CPU load acquired from a trace collection management table 106 and retrieves a trace data collection range 107 that is previously set to the number 114. Thus the program 105 collects the trace when a module name is set and then does not collect the trace when no module name is set respectively.
