The vRealize Operations for Published Applications desktop agent runs as a service on the XenDesktop Delivery Controller on each XenDesktop Session host server, Licence server, RDS host, Store Front server, and on all the VDI machines.

The desktop agent monitors Citrix ICA sessions and HDX sessions and applications launched in the Citrix ICA and HDX sessions by using standard functions and APIs of Windows OS. The desktop agent periodically collects the Citrix ICA sessions' data on properties and performance, and sends the data to the adapter using a secure connection.

The desktop agent service is configured to restart automatically by default. You can change the default configuration by accessing services.msc, right-click Desktop Agent Service, and select Properties > Recovery.
