Any UIM release
There was no value being produced for metric "LicensingGracePeriodTimesRemaining" on the Citrix side.
The following will help confirm if the relevant metric is being populated or not:
Login to the XenDesktop Controller as domain user Open PowerShell command prompt Run the following cmdlet for verification.
1.Add-PSSnapin Citrix.*.Admin.v2
2.Get-BrokerController
The output of the above commands should be key, value pairs including "LicensingGracePeriodTimesRemaining" as a key.
If the value for this is empty {} then this indicates that Citrix side configuration is required.
