Non-intrusive method for logging of internal events within an application process, and system implementing this method

Abstract

A method and computer system logs events occurring in an application in a single or multi-computer environment, functioning non-intrusively and transparently vis-á-vis this application. A first computer node receives a communication from a client; the first computer node executes a transactional application that provides services to the client. A process of the transactional application includes a call to a first function. In response to the call to the first function, a modified function is executed that calls both the first function and second recording function. The call to the recording function is detected at a secondary computer node, different from the first computer node. The recording function executes at the second node to store logged data at the second computer node, the logged data representing execution of the first process.
