• 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;
