A simple daemonized script to report Pi-Hole stats to an InfluxDB, ready to be displayed via Grafana.
As Pi-hole (as the name suggests) is built specifically with the Raspberry Pi in mind (and I run it on there as well), the following steps assume an instance of Pi-hole on Raspbian Strech Lite, with no additional modifications so far. Piholestatus will be configured to run on the same Pi.
First install the necessary packages via apt as Raspbian Lite does have neither git nor pip installed.
sudo apt update
sudo apt install git python-pip -yNow clone the repo, install the Python dependencies, and make sure to copy and adjust the example configuation file to match your setup.
git clone https://github.com/janw/pi-hole-influx.git ~/pi-hole-influx
cd ~/pi-hole-influx
# Install requirements via pip
pip install -r requirements.txt

Copy config.example and modify it (should be self-explanatory)
cp config.ini.example config.ini
vi config.iniBefore starting the daemon for the first time, symlink the systemd service into place, reload, and enable the service.
sudo ln -s /home/pi/pi-hole-influx/piholeinflux.service /etc/systemd/system/
sudo systemctl --system daemon-reload
sudo systemctl enable piholeinflux.serviceNow you're ready to start the daemon. Wait a few seconds to check its status.
sudo systemctl start piholeinflux.service
sudo systemctl status piholeinflux.serviceThe status should look as follows. Note the Status: line showing the last time, the daemon reported to InfluxDB:
● piholeinflux.service - Pi-hole-Influx - Send Pi-hole statistics to InfluxDB for visualization

The example dashboard seen at the top uses the collected data and displays it in concise and sensible graphs and single stats. The dashboard can be imported into your Grafana instance from the dashboard.json file included in the repo, or by using ID 6603 to import it from Grafana's Dashboard Directory.
The script originally created by Jon Hayward, adapted to work with InfluxDB by /u/tollsjo in December 2016, and improved and extended by @johnappletree. "If I have seen further it is by standing on the shoulders of giants". 🤓
