The system logs views from unauthorised domains (i.e. anything not included in permitted_domains).
Dashboard
The dashboard can be viewed at https://chrono.bentasker.co.uk/sources/0/dashboards/25
There is a free text variable field used to filter the domain name
Screenshots
In v0.2, the system would attempt to take a page screenshot (this functionality was removed in v0.3 / websites/privacy-sensitive-analytics#14).
The dashboard linked to above provides a list of these in the format mikasa:/mnt/images/screenshot_1648476636141.png
There's a utility in $PATH called fetch_screenshot.sh, so running
fetch_screenshot.sh mikasa:/mnt/images/screenshot_1648476636141.png
Will fetch that screenshot, open it in Okular and then remove the local copy once done.
