This is a known issue with monitor service on XenDesktop 7.8 and Director 7.8

For a workaround do the following:

1. Check if the data is present in the monitor database by running the below SQL query

SELECT COUNT(*)
  FROM [“Your Monitoring DB Name”].[MonitorData].[Machine]
  where CurrentRegistrationState != 1 and LifecycleState = 1

2. Restart the Monitor service

Problem Cause
