You can use goaccess to create a log every day to json, excluding IP while retaining stats for geolocation.

For this you can logrotate daily and run goaccess before rotation. I believe you can keep the server logs for a week for debugging while respecting GDPR.

For today's "realtime" data you can use goaccess on today's log on demand and use a cache.

You can write your custom stat viewers or use goaccess to view time range data from multiple json files.
