Intellij idea 13.1 how to check VM option for a running application

Hi I am new to Intellij , I am running a spring web services application on tomcat server.

While starting server I pass CONFIG_MODE , like -DCONFIG_MODE=DEV which tell which env it belongs to ( it is internal logic in my application to identify dev , qa ... env)

Somehow I believe VM machine options is passed wrongly. Now I want to check at runtime what are values for my VM parameters passed while starting application. Tried searching google but did not get anything useful , need your help in this.
