Just a word of warning. I was playing around with VisualVM. I connected it to a running instance of JBossAS 5.0.0.CR1 that was not doing anything. Suddenly, the app server became active. The CPU usage was still relatively low, but every 20 seconds I was getting a garbage collection. Apparently, just connecting VisualVM to a Java app causes objects and garbage to be created. I checked JConsole and it does not exhibit this behavior. This behavior makes VisualVM a poor choice for monitor Java applications in production. By the way, I was using the VisualVM from JDK 6u7, and I ran AS 5.0.0.CR1 on the same version. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4174698#...
