This is a Prometheus exporter for Pi-hole's Raspberry PI ad blocker.
Available Grafana Dasboards:
- Prometheus: Grafana Labs / JSON/Github --> Preview
- InfluxDB 2 (Flux): Grafana Labs / JSON/Github --> Preview
You can download the latest version of the binary built for your architecture here:
- Architecture i386 [ Linux / Windows ]
- Architecture amd64 [ Darwin / Linux / Windows ]
- Architecture arm [ Darwin / 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 '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 'PORT=9617' \
-p 9617:9617 \
ekofr/pihole-exporter:latestIf you are running pi-hole behind https, you must both set the PIHOLE_PROTOCOL environment variable
as well as include your ssl certificates to the docker image as it does not have any baked in:
$ docker run \
-e 'PIHOLE_PROTOCOL=https' \
-e 'PIHOLE_HOSTNAME=192.168.1.2' \
-e 'PIHOLE_PASSWORD=mypassword' \
-e 'PORT=9617' \
-v '/etc/ssl/certs:/etc/ssl/certs:ro' \
-p 9617:9617 \
ekofr/pihole-exporter:latest
A single instance of pihole-exporter can monitor multiple pi-holes instances. To do so, you can specify a list of hostnames, protocols, passwords/API tokens and ports by separating them with commas in their respective environment variable:
$ docker run \
-e 'PIHOLE_PROTOCOL=http,http,http" \
-e 'PIHOLE_HOSTNAME=192.168.1.2,192.168.1.3,192.168.1.4"' \
-e "PIHOLE_API_TOKEN=$API_TOKEN1,$API_TOKEN2,$API_TOKEN3" \
-e "PIHOLE_PORT=8080,8081,8080" \
-e 'PORT=9617' \
-p 9617:9617 \
ekofr/pihole-exporter:latest
If port, protocol and API token/password is the same for all instances, you can specify them only once:
$ docker run \
-e 'PIHOLE_PROTOCOL=http" \
-e 'PIHOLE_HOSTNAME=192.168.1.2,192.168.1.3,192.168.1.4"' \
-e "PIHOLE_API_TOKEN=$API_TOKEN" \
-e "PIHOLE_PORT=8080" \
-e 'PORT=9617' \
-p 9617:9617 \
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 install github.com/eko/pihole-exporter@latest
# or
$ git clone https://github.com/eko/pihole-exporter.gitInstall 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 azertyOr 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)

...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']# Hostname of the host(s) 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)
# Timeout to connect and retrieve data from a Pi-hole instance
-timeout duration (optional) (default 5s)
# WEBPASSWORD / api token defined on the Pi-hole interface at `/etc/pihole/setupVars.conf`
-pihole_api_token string (optional)
# Address to be used for the exporter
-bind_addr string (optional) (default "0.0.0.0")
# Port to be used for the exporter
-port string (optional) (default "9617")| Metric name | Description |
