DMS Spy Servlet to monitor/retrieve the metrics - Oracle SOA Suite platform
This post will explain how to monitor Oracle SOA Suite application through DMS Spy ServletThe DMS Spy servlet provides access to DMS metric data from a web browser. Data that is created and updated by DMS-enabled applications and components is accessible through the DMS Spy Servlet.
The DMS Spy Servlet is part of the DMS web application. The DMS web application's web archive file is dms.war, and can be found in the same directory as dms.jar: <ORACLE_HOME>/modules/oracle.dms_11.1.1/dms.war.
The DMS web application is deployed by default as part of a JRF-enabled server instance. The URL is: http://host:port/dms/Spy.
Only users who have Administrator role access can view this URL as access is controlled by standard Java EE elements in web.xml.
This can be used to monitor Oracle SOA Composites, SOA Components, JVM, Datasources and MDS etc..
How to get the metrics through wget command:
The required metrics can be retrieved through wget command and exported to a XML format.
Login to server to execute the Spy servlet
wget --save-cookies cookies.txt --keep-session-cookies --post-data "j_username=weblogic&j_password=password&j_character_encoding=UTF-8" --delete-after http://localhost:7201/dms/j_security_check
Invoke the Spy servlet to fetch the required metrics
wget64 --load-cookies cookies.txt "http://localhost:7201/dms/Spy?format=xml&cache=false&prefetch=false&table=JVM&orderby=Name" -O server_JVM_metrics.xml
This will export the JVM metrics in XML format to server_JVM_metrics.xml
