Intercepting and recording calls to a module in real-time

Abstract

Methods, systems and computer program products for intercepting and recording calls of a module in real-time is provided. Each listed target module is loaded into system memory. A link is established between each target module and the recording framework, which begins execution of an application that includes the plurality of target modules. In response to one of the plurality of target modules being called by the application, control is passed to the recording framework, which includes passing to the recording framework original registers from the application and a register containing an entry point of the recording framework. Recording framework records arguments passed to the target module. Tags identifying the execution environment, transaction name, transaction id, calling program name, and whether the call is for input or output are recorded. When the target module completes, control passes back to the recording framework, which records the output parameters from the target module.
