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.
