When on the View > XenApp & XenDesktop page, the page is blank and there are no sessions displayed.
The Topology View shows the error "required prereq is missing" (see image below).
Troubleshooting Steps:
When on the View > XenApp & XenDesktop page, check the bottom left corner to make sure that the page is not filtered (data is in the search pane).
When on the View > XenApp & XenDesktop page, try selecting each of the radio button options at the top. These pages will be filled in as applicable to your license/environment. (The options "App Servers" and "Published Apps & Desktops" are applicable to XenApp and "Virtual desktops" is applicable to XenDesktop.
Go to the Configure > Inventory page and make sure the line item(s) for your delivery controller(s) are showing a green box in the 'stat' column.
If there is a RED box, this indicates the delivery controllers are not connected.
Select the line item(s) for the delivery controller that is not connected and click the Edit button at the bottom of the page. A new window opens:
Does the delivery controller have an account applied to it in the "XenApp & XenDesktop monitoring" Section?
If no, proceed.
If yes:
Make sure that these settings are only configured on 1 delivery controller per Citrix site.
Make sure that the account listed has admin rights on the machine. This account is used to run the MonitorIT Agent Service. If this was not the case, you will need to manually start the MonitorIT Agent Service then allow about 5-10 mins for data to populate.
If there is a GREEN box, this means that the delivery controller is most likely missing the required rights.
Select the line item(s) for the delivery controller that is not connected and click the Edit button at the bottom of the page. A new window, opens:

If no, please see the knowledge base section of Goliath Performance Monitor > Monitor Your Environment for documentation on enabling Citrix monitoring.
Please note, only one delivery controller is required to be configured
If there is no box or line item this means Citrix monitoring has not been configured. Please see the knowledge base section of Goliath Performance Monitor > Monitor Your Environment for documentation on enabling Citrix monitoring.
