An information processing device for acquiring usage data of an application on the information processing device loads a monitoring library when an application is launched. The monitoring library intercepts event information arising from the application at some midpoint between the application and an operating system, or between the application and a library, selects some events among the event information, and interprets the selected events on the basis of a predetermined process. Then, the monitoring library sends the event information to a monitoring process. The monitoring process creates usage data on the basis of the event information and stores the usage data in a file.

1. A method used in an information processing device for acquiring usage data of an application on the information processing device, the method comprising the steps of:requesting the application to load a monitoring library by a control thread of a monitoring process when the application is launched; rewriting a head part of a program in a predetermined library by the monitoring library; inserting the monitoring library between the application and the predetermined library; launching, by the control thread, a monitoring thread for receiving event information from the monitoring library; intercepting one of a function call event and a function end event by the monitoring library when the application is used; selecting at least one function among event information and retaining argument information of the at least one function by the monitoring library based on application-specific information; sending the argument information to the monitoring thread by the monitoring library; creating the usage data based on the argument information by the monitoring thread; sending the usage data to a writing thread by the monitoring thread; and writing the usage data to a file by the writing thread.
