Last year at the San Francisco Synergy 2012 Citrix Tooling as a Service (TaaS) was introduced and the final version of this project is now available as Citrix Auto Support https://taas.citrix.com/AutoSupport/howitworks/
One of the goals the TaaS project team was working on included adding more automation into the product setup to make sure that everything has been installed and configured correctly after the setup.
The Excalibur Tech Preview is showing the first results of this effort, unfortunately most of these features have been disabled in the Tech Preview. The Citrix Studio management console in the Excalibur Tech Preview shows options to Test things like the Site configuration, Machine catalogs and Delivery Groups.
These features will make it easier to troubleshoot your XenDesktop environment. Tools like XDPing might not be required anymore in Excalibur (XenDesktop 6?)
I hope Citrix will release a full beta soon for Excalibur that will have all features enabled. At the Anaheim Synergy I expect Citrix will release more information on when the final version or a beta version will become available.
You can find a very good guide on how to setup the Excalibur Tech Preview here if want to give it a try.
