Cleaning Log Files
--------------------------------------------------------------------

# output current pihole db size
sudo du /etc/pihole/pihole-FTL.db -h
# flush pihole logs
pihole flush
# stop pihole FTL service
sudo systemctl stop pihole-FTL
# delete the FTL database file

Reduce Long Term Log Lifespan
--------------------------------------------------------------------
By default, Pi-hole keeps long term DNS logs for 365 days. This lifespan can be changed by altering the MAXDBDAYS variable in /etc/pihole/pihole-FTL.conf
01. To reduce the log lifespan, run the following commands in a terminal window
# edit pihole-FTD.conf
sudo nano /etc/pihole/pihole-FTL.conf
02. Add or edit MAXDBDAYS value in the configuration file as needed
03. Press CTRL+O, Enter, CTRL+X to write the changes
04. Continue with the following command
# restart pihole-FTL server
sudo systemctl restart pihole-FTL
05. After restarting the service the new logs lifespan will be active
