I'm currently settings up a brand new XenApp/Desktop 7.11 environment and during testing I'm also noticing the same issues with Director not display stats. Front page shows no sessions and average logon duration, trends is empty except for Machine Usage, Filters Active Machines/Sessions etc is also empty. I can see the servers and users fine if do manual search. Restarting the Citrix Monitor Service helped a little with User session/connections appearing in Filter list and User Details page now showing Logon Duration but that was it.
Also got same error message as Sacha Thomet in post #4 when I restarted the Citrix Monitor Service. I had no errors on any servers or session hosts prior to that though.
Citrix Studio Search has no issues displaying correct number of Server OS Machines and Session and is up to date and accurate, so looks to be just Director.
With regards to SPNs, mine were currently empty but I have now set them and I'm not seeing any improvement after rebooting servers / services / new connections etc.
I did get an extra error event log after restarting Citrix Monitor Service again after setting the SPN: -
Source: Citrix Director Service
Event ID: 2
An unexpected error occurred when accessing the data source 'unknown error.' (http://servername.domain.com/Citrix/Monitor/OData/v3').
Console operation: 'Searching and retrieving sessions...'
'Object reference not set to an instance of an object.'
