It might take some time before you start to see usable data.
Some things to check
1. Verify network policy has the correct time (verify NTP or SSH in AP and do a "show clock" or show time, and show ntp) 2. If you are using Private Cloud (HM On Premises) then verify HiveManager has the correct time (easy to check in the screenshot it says its August 16 around 11:44 AM), if you are using HMOL then you don't have to worry about this..
