Citrix Director displays blank/missing logon durations and exhibits delays populating real-time session details.
The Citrix-XenDesktop-BrokerMonitor/Operational event log channel on the Delivery Controllers is either excluded, unforwarded, or restricted due to a Windows Event Forwarding (WEF) subscription or Group Policy configuration.
Remove the Windows Event Forwarding policy settings applied to the Delivery controllers.
Open Group Policy Management (gpmc.msc) on a Domain Controller or RSAT machine.
Expand your domain tree and locate the Organizational Unit (OU) where the WEF GPO is linked.
Unlink or Delete:
To temporarily disable for a target OU: Right-click the GPO under the OU and uncheck Link Enabled, or right-click and choose Delete (this unlinks it from the OU without deleting the GPO itself).
To remove permanently across the domain: Right-click the GPO under Group Policy Objects and select Delete.
