Application Monitoring

JMX

There is a variety of application information that can be accessed using the Java Management Extensions (JMX). This information can be accessed in a customized fashion using the JMX API, or more generically using popular JMX clients like jconsole, jvisualvm, and so on.

JMX connections can be made by adding the appropriate Java options in Tomcat. These options have already been added to the setenv.sh and setenv.bat files in the Advisors installation Tomcat bin directory. Uncommenting these options and adding the port and host information for your environment will allow you to establish JMX connections.
