The present invention relates to a program for causing an information processing device in an information processing system including the information processing device to execute the steps of: executing at least one processing block executed in common when at least two types of commands for controlling the information processing system are respectively executed; storing determination values which are set for the respective types of the commands and which are used to determine whether log data to be outputted by executing the processing block needs to be outputted; and storing results of determining whether the determination values satisfy a log data output condition set for the processing block when the processing block containing an algorithm for outputting the log data is executed.
