Looks like the data actually is calculated by lemmy not the logging tool as it is just the stats from the Aussie Zone public api…

Eg. id":1,“site_id”:1,“users”:1319,“posts”:1228,“comments”:13307,“communities”:32,“users_active_day”:170,“users_active_week”:300,“users_active_month”:481,“users_active_half_year”:481}

So the answer would actually be in the lemmy documentation…
