Setup

pip

PyPI

pip3 install --upgrade pihole_exporter

github master branch

pip3 install --upgrade git+https://github.com/dr1s/pihole_exporter.py.git

manual

git clone https://github.com/dr1s/pihole_exporter.py.git
cd pihole_exporter.py
pip3 install -r requirements.txt
cd pihole_exporter
./pihole_exporter.py

Docker

docker-hub

docker pull dr1s/pihole_exporter
docker run --net=host -v /etc/pihole:/etc/pihole -t dr1s/pihole_exporter

manual

git clone https://github.com/dr1s/pihole_exporter.py.git
docker build -t dr1s/pihole_exporter .
docker run -d --net=host -v /etc/pihole:/etc/pihole -t dr1s/pihole_exporter

Usage

usage: pihole_exporter.py [-h] [-o PIHOLE] [-p PORT] [-i INTERFACE] [-a AUTH]

pihole_exporter

optional arguments:
-h, --help            show this help message and exit
-o PIHOLE, --pihole PIHOLE
										pihole adress
-p PORT, --port PORT  port pihole_exporter is listening on
-i INTERFACE, --interface INTERFACE
								interface pihole_exporter will listen on
-a AUTH, --auth AUTH  Pihole password hash

pihole_exporter

Authentication

If pihole_exporter is installed on the same host as pihole and the auth argument is not set, pihole_exporter will try to read the password from setupVars.conf

Otherwise get the hashed password from setupVars.conf:

$ grep WEBPASSWORD /etc/pihole/setupVars.conf
WEBPASSWORD=da1a51f575cd740be233d22548ecac1dbcc96ffa297283a6a204f9213a8aca71

Use this hash as the argument for --auth

pihole_exporter --auth da1a51f575cd740be233d22548ecac1dbcc96ffa297283a6a204f9213a8aca71
docker run -d --net=host -t dr1s/pihole_exporter --pihole pi.hole --auth da1a51f575cd740be233d22548ecac1dbcc96ffa297283a6a204f9213a8aca71
