# Pi-hole-Influx

A simple daemonized script to report Pi-Hole stats to an InfluxDB v2 instance, ready to be displayed via Grafana.
**⚠️ The docker image name has been changed to `ghcr.io/janw/pi-hole-influx`. Please update your deployment accordingly. If you are still using InfluxDB v1, please use [version 1.0](https://github.com/janw/pi-hole-influx/releases/tag/v1.0.0) (`ghcr.io/janw/pi-hole-influx:v1`) of Pi-hole-Influx. Newer versions (tagged `:v2` and `:latest`) only support InfluxDB v2. ⚠️**
## Setup (Using Docker)
* To use docker for running the daemon, use the following command:
```bash
docker run \
-e PIHOLE_INFLUXDB_URL=https://127.0.0.1:8086 \
-e PIHOLE_INFLUXDB_BUCKET=mybucket \
-e PIHOLE_INFLUXDB_TOKEN=mytoken \
-e PIHOLE_INFLUXDB_ORG=myorg \
-e PIHOLE_INSTANCES='[{
"name": "pihole",
"base_url": "http://127.0.0.1",
"api_token": ""
}]' \
--network host \
ghcr.io/janw/pi-hole-influx:v2
```
where `PIHOLE_INSTANCES` is a JSON-formatted list of instances to monitor with required fields of `name` and `base_url` and an (theorically optional but generally required) `api_token` (see below).
### Authentication
Newer versions of Pi-hole [require authentication when accessing the API](https://pi-hole.net/blog/2022/11/17/upcoming-changes-authentication-for-more-api-endpoints-required/#page-content) of an instance that has been configured with a web-interface password. If that is the case for your instance (as it should be), please make sure to include the `api_token` in the instance config. You can find in the Pi-hole admin panel under Settings -> API / Web interface -> Show API token.
### Configuration file
An alternative to configure Pi-hole-Influx through environment variables is a TOML-formatted configuration file. See [user.toml.example](user.toml.example) for an example configuration. It can be mounted into the container under `/config/user.toml` to provide the configuration instead.
## Docker-compose example
If you want to run the daemon through Docker-compose, you might appreciate the configuration example below.
```yaml
version: "2"
services:
piholeinflux:
image: ghcr.io/janw/pi-hole-influx:v2
container_name: piholeinflux
restart: unless-stopped
environment:
# Replace details with your InfluxDB's hostname and credentials
PIHOLE_INFLUXDB_URL: "http://10.10.10.1:8086"
PIHOLE_INFLUXDB_TOKEN: "mytoken"
PIHOLE_INFLUXDB_BUCKET: "pihole"
PIHOLE_INFLUXDB_ORG: "eee0001234asdf"
# Replace with your Pi-Hole's base_url and api_token below
PIHOLE_INSTANCES: |
[{
"name": "pihole",
"base_url": "https://127.0.0.1",
"api_token": ""
}]
# Additional options that can be adjusted
PIHOLE_REQUEST_TIMEOUT: "15" # seconds
PIHOLE_REQUEST_VERIFY_SSL: "False"
PIHOLE_REPORTING_INTERVAL: "90" # seconds
# OPTIONAL: Instead of the aobove environment variables,
# use a custom copy of the user.toml config file.
volumes:
- ./custom/config.toml:/config/user.toml
```
## Setup (Traditional Way)
As Pi-hole (as the name suggests) is built specifically with the Raspberry Pi in mind, the following steps assume an instance of Pi-hole running on a Raspbian installation, with no additional modifications. Pi-hole-Influx 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.
```bash
sudo apt update
sudo apt install git python3-pip -y
```
Now clone the repo, install the Python dependencies, and make sure to copy and adjust the example configuation file to match your setup.
```bash
git clone https://github.com/janw/pi-hole-influx.git ~/pi-hole-influx
cd ~/pi-hole-influx
# Install requirements via pip
pip3 install -r requirements.txt
# Copy config.example and modify it (should be self-explanatory)
cp user.toml.example user.toml
vi user.toml
```
Before starting the daemon for the first time, symlink the systemd service into place, reload, and enable the service. Note that if you are using a user that isn't `pi`, you must edit piholeinflux.service and change the `User` and `WorkingDirectory` to match yours.
```bash
sudo cp piholeinflux.service /etc/systemd/system/
sudo systemctl --system daemon-reload
sudo systemctl enable piholeinflux.service
```
Now you're ready to start the daemon. Wait a few seconds to check its status.
```bash
$ sudo systemctl start piholeinflux.service
$ sudo systemctl status piholeinflux.service

## Set up a Grafana Dashboard
The example dashboard seen [at the top](#pi-hole-influx) 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](https://grafana.com/dashboards/6603).
