When i was developing an application for a large group of users it is a question how it performs in real production situations.
To measure it i found a very nice tool. It is AppDynamics and it has a lite version witch is free for downloading and using it !!! ( http://www.appdynamics.com / http://www.codecentric.nl )
When i downloaded it doesn't work when i followed the manual. I can measure my Eclipse an SoapUI but not my JBoss 7.0.2
Finaly it works with a little configuration :
- unzip AppDynamicsLite.zip and all zips in it in the directory /opt/java/AppDynamicsLite
- Go to your JBoss directory and edit standalone.conf
Add the following line to it :
# APPDynamics
JAVA_OPTS="$JAVA_OPTS -javaagent:/opt/java/AppDynamicsLite/javaagent.jar -Djboss.modules.system.pkgs=com.singularity"
After that you can start JBoss ( standalone ) and the AppDynamicsLite tool to measure and improve your application.
