Check client events in ePO console for DAT update with Site, this will define if machines are taking DAT update from your Super Agent or not.
There is already a peconfigured ePO query, Go to Query tab in ePO console and search for Repository, A list will appear and navigate to query "Repository Utilization" run that query.
If your neawly build repository is having some associated machine event counts which means its working fine and giving updates to Clients.
Thanks a lot!
I worked on those reports, they show all events but can figure out if the repository is on use or not.
