PROBLEM TO BE SOLVED: To provide a computer system which can efficiently collect information for investigating the fault of software. SOLUTION: A tracing function for collecting tracing information for tracking the execution process of a program in a tracing area 23 is provided for the computer system which properly samples a check point image in a check point area 22 for restating an interrupted processing. When the computer system normally operates, tracing information is not collected into the tracing area 23 by the tracing function. When the check point image sampled into the check point area 22 by means of the fault is restored and the processing is restarted, the collection of tracing information into the tracing area 23 by the tracing function is started. Thus, tracing information required for the analysis of the fault can be sampled without generating overhead for sampling tracing information at the time of the regular operation. |
