PROBLEM TO BE SOLVED: To provide a trace device that can suppress increase in CPU load upon output processing of program operation information without adding exclusive hardware, and can record the program operation information without being affected by system down (or an operation situation of a system operation system). ! SOLUTION: A trace device 1001 incorporating a multicore processor including a plurality of CPUs 101-1 to 101-3 and 201, the trace device 1001 comprises: a system operation system 100 that runs a program using the CPUs 101-1 to 101-3, and collects program operation information indicative of an operation history of the program; and a log control system 200 that operates independently of a system operation system 100 without being affected by an operation situation of the system operation system 100 using the CPU 201, and outputs the program operation information collected by the system operation system 100 to an IO device 1. !
