Microsoft recently announced a new service for VS Online called Application Insights (This is an invite-only service at the time of this writing). In addition to providing deeper insight into your .NET applications, this online solution also has the ability to monitor your Java application as well. Very similar to the Application Performance Management (APM) pieces available for monitoring your System Center Operations Manager, there is a capability of monitoring Java processes deployed anywhere (in any cloud or on premise).
The initial release targets supports for Tomcat 6, Tomcat 7, or JBoss 6. If you have more questions, please post them in the Visual Studio Forums.
