Information processing apparatus with log output function, mobile terminal device, and log output control method

A log output control method executed in an information processing unit that executes a program module under control of an operating system, the method comprising:

• loading, when the operating system is activated, a log output module that is a program module that outputs, as a log, information related to an access request between the operating system and a hardware resource when the access request is generated, when a log mode that is an operating state to collect information related to an operation is set in the information processing apparatus;
• and
• outputting the information related to the access request according to the loaded log output module.

A portable terminal apparatus that executes a program module under control of an operating system, the apparatus comprising:

• a state determining unit that determines whether or not a state exists to switch to a log mode that is an operating state for collecting information related to an operation to the corresponding device;
• and
• a log mode control unit that, when it is determined that the state to switch the log mode exists, causes a log output module that is a program module having a command to output, to a log, information related to an access request between the operating system and a hardware resource when the access request is generated, to be loaded during activation processing of the operating system.
