• As e-commerce becomes more popular, the performance of enterprise web applications becomes an important and challenging issue. Unlike failures, performance degradation is more difficult for the administrator to observe. It also takes much time to locate the root cause because there are many possible performance bottlenecks including network I/O, resource starvation, source code mistakes and even high site requests.
  In this thesis, we propose a system which is able to detect and diagnose web application performance degradations at the method call level in real time. We also set four sensors on the web server to monitor web application conditions, and use the measurements as input in detection and diagnostic algorithms. We implement our system in Java and build a test bed using a pet store application. Our system is evaluated on the test bed and results are encouraging, showing that our approach outperforms a traditional detection approach.
