Citrix Monitoring Anyone?

Greetings All!

I am designing my Xymon setup, and in reading some of the material I've discovered that Xymon is capable of a limited view of Citrix, that limit being the ability to see only the number of users connected. 

Has anyone been able to also add the ability to see who is logged on, the date/time of their login as well?

Of course, any other info too would be great to have.

Thank you!
