PROBLEM TO BE SOLVED: To efficiently store the useful information for specifying the cause even when a CPU runs away or stops. SOLUTION: This trouble monitoring device of a CPU system 4 where a CPU 1 and a peripheral circuit 2 including one or more functioning devices 2a to 2b for realizing predetermined functions are connected through a common bus 3 to each other is provided with a detecting means 6 for detecting a predetermined state that any trouble may be generated in the processing of the CPU 1 based on a predetermined signal capable of estimating the operating condition of the CPU 1 from the outside and a log information recording means 7 for acquiring a predetermined signal transferred between the CPU 1 and the peripheral circuit 2 according as the predetermined state is detected, and for recording the predetermined signal in a non-volatile memory 8.
