Using the tests mapped to this layer, you can measure the following for the configuration on the single node on which the target web server instance is running:

  • The quality of the HTTP requests to and from the web server instance;
  • The session activity on the web applications deployed on the virtual servers for the configuration;
  • The responsiveness of and the traffic handled by the web server instance;
  • The memory usage and thread usage of the web server instance;
  • The current size and usage of the connection queues of the web server instance;
  • How effectively the DNS cache and file cache were utilized by the server instance;
  • The overall health of the JVM of the web server instance;
  • The request processing ability of the web server instance measured on the basis of thread pool usage;
