DMS Spy Servlet is a small web-based application that displays Dynamic Monitoring Service (DMS) related metrics, which are built-in metrics automatically collected by the servers. Simply navigate to the URL
http://<host>:<soaport>/dms/Spy and log in using the administrator account (for example, weblogic).
You can retrieve an immediate snapshot on everything from running JDBC statements to JVM threads to MDS repository configuration to numerous Oracle WebLogic Server metrics.
The DMS Spy Servlet is perhaps the easiest way to quickly get instant monitoring information. Additional information about DMS Spy Servlet can be found on the Oracle documentation site at http://docs.oracle.com/cd/E15586_01/core.1111/e10108/monitor.htm#CFAHIAIB.
