How to instrument a custom Java application with ITCAM for J2EE?
Answer
If you are using a Custom java app that doesn't use one of the standard supported J2EE servers like WebSphere, WebLogic, Tomcat, JBoss, etc.. and you want to monitor this custom java application/server, then follow these steps to monitor it.
1. First find the main class being used in your application. In this example, am using the ThreadExample.jar. If I do jar -xvf ThreadExample.jar, this will extract out the directory and the MANIFEST.MF file. See screenshots here.
2. Now look at the MANIFEST.mf file under the META-INF directory. You will see the Main Class being used here:
3. Now run the ITCAM configuration GUI and you will use the main class specified in the GUI. You will also specify the startup script being used to start the application/server. (Note: If you do not use a startup script, then you will have to modify the original startup script to use the JAVA_OPTS variable as shown in the example here..)
Here's the original startup script before the ITCAM modifications.
Here's how the startup script gets modified with the ITCAM arguments in it.
4. So when the script starts up now, it will use the JAVA_OPTS environment variable and use the instrumented ITCAM arguments when starting the custom java application.
