Monitoring with the Administration Console

Thus far in this book, you've learned how to use the Administration Console to configure various aspects of a WebLogic Server environment. For a WebLogic Server administrator, the console is equally indispensable for monitoring running server instances, including the various subsystems such as security, JTA, and JDBC. Let's quickly review the most important server monitoring features that you can access through the Administration Console.

To access the main monitoring page for a domain, go to Environment | Servers and click the Admin Server link. In the Settings for <server_name> page, click the Monitoring tab. The main monitoring page itself really has no details about the running instance, other than its state (RUNNING, for example). However, you can monitor all aspects of a running server instance by clicking the various subtabs on this page, such as JDBC, JMS, JTA, SAF, and so on, to drill down to the individual services. Following is a brief explanation of the key pages you can reach from the main monitoring page.
