Method, program, and storage medium for acquiring logs

A log acquisition method for acquiring a runtime log of a program including a method for performing a predetermined process, comprising the step of:

• changing the address of said method loaded for performing said predetermined process to the address of a method for log acquisition,
• wherein said method for log acquisition comprises the steps of:
• calling said method for performing said predetermined process to cause said predetermined process to be executed, receiving the result of the execution, and passing said result to said program;
• recording given information when calling said method for performing said predetermined process;
• and
