The DMS Spy Servlet is a small web-based application that displays metrics related to Dynamic Monitoring Service (DMS), which are built-in metrics that are automatically collected by the server. Simply navigate to the following URL on the AdminServer (http://adminhost:7001/dms/Spy) and log in using the administrator account (for example, weblogic).

You can retrieve an immediate snapshot of everything from running JDBC statements to JVM threads to MDS repository configuration to numerous Oracle WebLogic Server metrics, as shown in the following screenshot:

The DMS Spy Servlet is perhaps the easiest way to quickly get instant monitoring information, but it does not maintain history. These DMS metrics can be retrieved using the command line as well.
