Thank you for you two for bothering. I had access to the system at the end of the weeked - that is why I could not test anything before.
Resolution:
The reboot of the view connection servers changed everything, and suddenly I had events and inventory in my pool (and saw vCenter cloning workstations).
The reboot of the vCenter server or the restart of the services on servers was not enough to solve this for me. I have a new perspective on how to operate
view now, thank you for that.
