Monitoring Web Applications

You can monitor web applications, and the servlets and JSPs contained in them, by using the Administration Console. Choose the Deployments/Web Application Modules to list each web application, together with its context root and deployment order. If you customize the view, you will be able to view further information, such as the security authentication realm associated with the web application and the servlet's reload period.

From the Servlets tab (the Monitoring tab in WebLogic 7.0), you can view statistics on each servlet, such as the number of times it has been invoked and its average execution time. You also can customize the view and obtain further information, such as the full classname of the servlet and the number of times the servlet was reloaded. By default, the servlet with the name /* is the FileServlet, which serves any request for static files. JSPs also are listed here because they, too, are servlets.

You can gather further statistics about sessions, but to do so you have to first enable session monitoring. You can do this by selecting the Sessions tab and enabling the option. You also can enable this option for a web application from its Configuration/Descriptor tab. Once you've enabled session monitoring, you can then view the list of active sessions from the Monitoring/Sessions tab. This includes data such as the session identifier, the server to which the session is bound, and at the time the session was last accessed.
