If I “Fetch event” in an anomaly detection, would this generate costs in the platform based on scanned event in Grail based on each Anomaly Detection execution (check)?

Hi,  
I think `fetch dt.system.events` is not billiable.  
Best regards

The fetch events or fetch bizevents do generate query costs while fetch dt.system.events does not.
