PROBLEM TO BE SOLVED: To correctly connect log information separately outputted to plural files along the time base, and to accurately grasp the order of the generation of events from the connected log information. SOLUTION: Each program 101, 102, and 103 in a software system 111 obtains a shared counter value for specifying the order of output of log information held by a shared counter 110, and outputs the value by including it in log information, and stores it in a log information file. The shared counter value obtained by the shared library 103 at the time of outputting the log information is notified through a shared counter value notifying means 108 to the program 102 calling another program (the shared library 103 in Figure), and the notified shared counter value is outputted so as to be included in the log information. Thus, the order of output of the log information can be uniquely specified, and the relevance among the plural log information can be clarified by using the shared counter values recorded on the plural log information in the plural log information files and the notified shared counter value.
