Reporting->Insight : no data after upgrade

[planetf1]

I updated from 24.7.12 to 25.1rc1 via a full upgrade (boot/config import).

Generally opnsense is working well. However I've noticed that I am not seeing any insight data (Reporting->Insight). No data in graphs or tables. Netflow is enabled on wan+lan & appears to be configured correctly, as it was with 24.7.12

I've also used 'repair netflow data' and much later 'reset netflow data' which has not made any difference

Answering my own question - I realised the 'insight aggregator' was not actually running. Not sure why not as insight was enabled. I've not rebooted yet so will watch out to see if it comes back. Anyway, it's working ...
