Note that one profiler may work better than another for your application. 

Visual VM

VisualVM is a stand-alone profiler that comes with the Java JDK distribution from Oracle.   Note that the version number of the code in your JDK may be higher than that shown on the Visual VM web site.

The VisualVM application is located in the "bin" folder of your JDK installation directory and is called "jvisualvm.exe" (Windows) or something similar.

Start Visual VM before you start your Java application.

JVM Monitor

Check the JVM Monitor website for the latest update URL for Eclipse. 

Update site for JVM Monitor 3.8:   http://www.jvmmonitor.org/updates/3.8

Be sure to switch to the "Java Monitor" perspective before starting the application you wish to profile.
