A precise execution tracing is essential to help both developers and administrators debug performance problems of multi-tier web applications. This paper introduces a non-intrusive end-to-end runtime path tracing method, which does not require instrumentation of middleware or application source code, but is limited to co-located web/application server environments. We present the design and implementation in detail, and develop a tool named ExeTracer. Further, we evaluate the performance overhead associated with the tool. The results show that the low performance overhead makes it a promising tracing tool for using on multi-tier web applications.
Keywords:computer software and theory; web application; execution trace; runtime path
