|
## Prerequisites
|
|
|
|
* [Go](https://golang.org/doc/)
|
|
|
|
## Installation
|
|
|
|
### Download binary
|
|
|
|
You can download the latest version of the binary built for your architecture here:

|
|
]
|
|
|
|
### Using Docker
|
|
|
|
The exporter is also available as a [Docker image](https://hub.docker.com/r/ekofr/pihole-exporter).
|
|
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
|
|
|
|
```bash
|
|
$ 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:latest
|
|
```
|
|
|
|
If 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
|
|
```
|
|
|
|
### From sources
|
|
|
|
Optionally, you can download and build it from the sources. You have to retrieve the project sources by using one of the following way:
|
|
```bash
|
|
$ go install github.com/eko/pihole-exporter@latest
|
|
# 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):
|
|
```bash
|
|
$ GOOS=linux GOARCH=arm GOARM=7 go build -o pihole_exporter .
|
|
```
|
|
|
|
## Usage
|
|
|
|
In order to run the exporter, type the following command (arguments are optional):
|
|
|
|
Using a password
|
|
|
|
```bash
|
|
$ ./pihole_exporter -pihole_hostname 192.168.1.10 -pihole_password azerty
|
|
```
|
|
|
|
Or use PiHole's `WEBPASSWORD` as an API token instead of the password
|
|
|
|
```bash
|
|
$ 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
|
|
```
|
|
|
|
```bash

Once the exporter is running, you also have to update your `prometheus.yml` configuration to let it scrape the exporter:
|
|
|
|
```yaml
|
|
scrape_configs:
|
|
- job_name: 'pihole'
|
|
static_configs:
|
|
- targets: ['localhost:9617']
|
|
```
|
|
|
|
