This is a Prometheus exporter for PI-Hole's Raspberry PI ad blocker.
Grafana dashboard is available here on the Grafana dashboard website and also here on the GitHub repository.
You can download the latest version of the binary built for your architecture here:
- Architecture i386 [ Darwin / Linux / Windows ]
- Architecture amd64 [ Darwin / Linux / Windows ]
- Architecture arm [ Linux ]
The exporter is also available as a Docker image. You can run it using the following example and pass configuration environment variables:
$ docker run \
-e 'PIHOLE_HOSTNAME=192.168.1.2' \
-e 'PIHOLE_PASSWORD=mypassword' \
-e 'INTERVAL=30s' \
-e 'PORT=9617' \
-p 9617:9617 \
ekofr/pihole-exporter:latest
Or use PiHole's WEBPASSWORD
as an API token instead of the password
$ API_TOKEN=$(awk -F= -v key="WEBPASSWORD" '$1==key {print $2}' /etc/pihole/setupVars.conf)
$ docker run \
-e 'PIHOLE_HOSTNAME=192.168.1.2' \
-e "PIHOLE_API_TOKEN=$API_TOKEN" \
-e 'INTERVAL=30s' \
-e 'PORT=9617' \
ekofr/pihole-exporter:latest
Optionally, you can download and build it from the sources. You have to retrieve the project sources by using one of the following way:
$ go get -u github.com/eko/pihole-exporter
# or
$ git clone https://github.com/eko/pihole-exporter.git
Install the needed vendors:
$ GO111MODULE=on go mod vendor
Then, build the binary (here, an example to run on Raspberry PI ARM architecture):
$ GOOS=linux GOARCH=arm GOARM=7 go build -o pihole_exporter .
In order to run the exporter, type the following command (arguments are optional):
Using a password
$ ./pihole_exporter -pihole_hostname 192.168.1.10 -pihole_password azerty
Or use PiHole's WEBPASSWORD
as an API token instead of the password
$ API_TOKEN=$(awk -F= -v key="WEBPASSWORD" '$1==key {print $2}' /etc/pihole/setupVars.conf)
$ ./pihole_exporter -pihole_hostname 192.168.1.10 -pihole_api_token $API_TOKEN

Once the exporter is running, you also have to update your prometheus.yml
configuration to let it scrape the exporter:
scrape_configs:
- job_name: 'pihole'
static_configs:
- targets: ['localhost:9617']
# Interval of time the exporter will fetch data from PI-Hole
-interval duration (optional) (default 10s)
# Hostname of the Raspberry PI where PI-Hole is installed
-pihole_hostname string (optional) (default "127.0.0.1")
# Password defined on the PI-Hole interface
-pihole_password string (optional)
# WEBPASSWORD / api token defined on the PI-Hole interface at `/etc/pihole/setupVars.conf`
-pihole_api_token string (optional)
# Port to be used for the exporter
-port string (optional) (default "9617")
