Websphere Application Server (WAS) v9 monitoring using SiteScope JMX Monitor

I am in the process of developing a monitoring approach for monitoring our WebSphere AS environments.  SiteScope does not currently support WebSphere AS (WAS) v9.x, so I was going to use the SiteScope JMX monitor.  After configuring the JMX monitor and pulling counters, I am not seeing the data I would expect from the JMX counters.  Items like the WAS application status and items like that are not present.  I am assuming I am missing a classpath, or something along those lines.

Has anyone else used JMX to monitor any WebSphere environments?  Any tips or tricks would be appreciated.
