while the former xenapp probe reported Application usercount as a QoS, the newer xendesktop probe does not have such a metric, nor does the Application Dashlet of the CABI probe visualize such Data.
This information was very helpful for administering a Citrix Application Delivery Platform. My and our customer improvement suggestion is to add this information to the Dashlet allowing Citrix Xendesktop
Below Screens document close what I'm looking for and how to get to the Dashlet in question. It starts at the second level dashboard of the Citrix Xendesktop Initial Dashboard.
Don't know how many customers are using this functionality. Nevertheless I hope that product management is looking at these ideas and see that we lost functionality between xenapp and xendesktop and can find a benefit to add this again without many votes.
