Log output control method, log output controller and recording medium storing log output control program

TL;DR: In this paper, the problem of obtaining a desired program without changing a job program mounted on a computer by outputting log message data to a log output file when the rank is not less than a log level was solved.

Abstract: PROBLEM TO BE SOLVED: To obtain a desired program without changing a job program mounted on a computer by outputting log message data to a log output file when the rank is not less than a log level and preventing it from being outputted when the rank is below the log level. SOLUTION: The basic function part 10 of a computer has a program file 13, a log message file 14, a log output file 15 and the like. In the output control method, ranking is executed by individual log message data and the log level of an output object is previously set. When log message data is generated in a process where a job program is executed, the rank of log message data is obtained. When the obtained rank is not less than the log level of the output object, log message data is outputted to the log output file 15. When the rank is below the log level, log message data is prevented form being outputted to the log output file 15.
