It would be amazing to add a screen or report type in the long-term data screen to show a deduped list of domain names visited in a given interval (day, week, etc.).
This will make log analysis so much easier.
First look up deduped names, then, if something interesting is seen, dig into that specific domain.
Currently, one could do this via SSH with:
holed -
cat pihole.log | awk '($8=="0.0.0.0") {print}' | awk '!blocked[$6]++ {print $6}'
allowed -
cat pihole.log | awk '($8!="0.0.0.0" && $7=="is") {print}' | grep 'Jan 19' | awk '!allow[$6]++ {print $6}'
