<p>PURPOSE:To prevent the trace information omission by constituting the subject system so that a trace information collecting processor executes a synchronous notice to a trace information obtaining processor at timing by which an exactly half of an intermediate buffer is utilized, and actuates the trace information acquiring processor. CONSTITUTION:When a trace information collecting request is outputted, a trace information collecting processor 20 executes an initialization for an operation to a control information area 41 of an intermediate memory 40 if necessary, and thereafter, writes trace information in an intermediate buffer area 42 of the intermediate memory 40. Also, whenever half of the intermediate buffer area 42 is used for writing, a synchronous notice is outputted through a synchronization informing device 30. A trace information acquiring processor 50 starts to acquire the trace information from a half area of the intermediate buffer area 42 in which the trace information is written, in accordance with the synchronous notice, and stores the acquired trace information in an external file 70 through a file I/O processor 60. In such a way, no excessive load is supplied to the trace information collecting processor 20, and the information omission can be prevented.</p> |
