The Logon performance in Director don't show any data for Group Policy. The values GpoStartDate and GpoEndDate are set to NULL in the table MonitorData.Connection.

After moving the server to an OU without any GPOs, director is showing the details correctly. This proves that the time taken by gpsvc processing is causing the monitor plugin to discard the data and hence Director does not show any value. Fixing the long time taken by Gpsvc will fix the problem of missing Logon Duration in Director.

Problem Cause

The GP start/end time is reported for the session based on the policy processing start/end time reported in eventlog by GpSvc. If the policy processing reported by GPSVC goes way past the User Logon phase and Shell start phase it will not be reported as part of the HDX Logon Duration payload. When GPO phase duration exceeds certain percentage of the logon duration we calculated, that value is ignored.
