AdGuard Home Prometheus Exporter

This is a Prometheus exporter for AdGuard Home.

Installation

Using Docker

You can run it using the following example and pass configuration environment variables:

$ docker run \
  -e 'ADGUARD_SERVERS=http://192.168.1.2' \
  -e 'ADGUARD_USERNAMES=demo' \
  -e 'ADGUARD_PASSWORDS=mypassword' \
  -e 'INTERVAL=15s' \ # Optional, defaults to 30s
  -p 9618:9618 \
  ghcr.io/henrywhitaker3/adguard-exporter:latest

A single instance of adguard-exporter can monitor multiple AdGuard Home instances. To do so, you can specify a list of servers, usernames and passwords by separating them with commas in their respective environment variable:

$ docker run \
  -e 'ADGUARD_SERVERS=http://192.168.1.2,http://192.168.1.3,http://192.168.1.4"' \
  -e "ADGUARD_USERNAMES=$USERNAME1,$USERNAME2,$USERNAME3" \
  -e "ADGUARD_PASSWORDS=$PASSWORD1,$PASSWORD2,$PASSWORD3" \
  -p 9618:9618 \
  ghcr.io/henrywhitaker3/adguard-exporter:latest

Env Vars

Variable	Description	Required	Default
ADGUARD_SERVERS	The servers you want the exporter to scrape. Must include the scheme http(s) and port if non-standard.	True
ADGUARD_USERNAMES	The username to connect to the adguard api with. Must be in the same order as ADGUARD_SERVERS if scraping multiple instances.	True
ADGUARD_PASSWORDS	The password to connect to the adguard api with. Must be in the same order as ADGUARD_SERVERS if scraping multiple instances.	True
INTERVAL	The interval that the exporter scrapes metrics from the server	False	30s
DEBUG	Turns on the go profiler	False	false

Usage

Once the exporter is running, you also have to update your prometheus.yml configuration to let it scrape the exporter:

scrape_configs:
  - job_name: 'adguard'
    static_configs:
      - targets: ['localhost:9618']

If you want to strip the scheme and port out of the server label in the metrics, you can add a relabeling:

- action: replace
  sourceLabels: ["server"]
  regex: http(|s):\/\/([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}).*
  replacement: $2
  targetLabel: server
