I am getting no data from horizon view adapter. any idea?
This is typically an indication of the Horizon license not being added to vROps for the Horizon adapter, and the configuration of license groups in vROps.
Check the broker agent on your View connection server. Make sure it is paired correctly with the vROps node that the View adapter instance is running on. If it all looks good try restarting the broker agent service.
What version of the Horizon adapter and Broker Agent do you have running? Also, did you do an upgrade to your Broker Agent recently?
