# AdguardHome Prometheus Exporter ![Build/Push (master)](https://github.com/ebrianne/adguard-exporter/workflows/Build/Push%20(master)/badge.svg?branch=master) [![GoDoc](https://godoc.org/github.com/ebrianne/adguard-exporter?status.png)](https://godoc.org/github.com/ebrianne/adguard-exporter) [![GoReportCard](https://goreportcard.com/badge/github.com/ebrianne/adguard-exporter)](https://goreportcard.com/report/github.com/ebrianne/adguard-exporter) ![DockerPulls](https://img.shields.io/docker/pulls/ebrianne/adguard-exporter) This is a Prometheus exporter for [AdguardHome](https://github.com/AdguardTeam/AdguardHome)'s Raspberry PI ad blocker. It is based on the famous pihole-exporter [available here](https://github.com/eko/pihole-exporter/) ![Grafana dashboard](https://raw.githubusercontent.com/ebrianne/adguard-exporter/master/grafana/dashboard.png) Grafana dashboard is [available here](https://grafana.com/dashboards/13330) on the Grafana dashboard website and also [here](https://raw.githubusercontent.com/ebrianne/adguard-exporter/master/grafana/dashboard.json) on the GitHub repository. ## Prerequisites * [Go](https://golang.org/doc/) ## Installation ### Download binary You can download the latest version of the binary built for your architecture here: * Architecture **i386** [ [Darwin](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-darwin-386) / [FreeBSD](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-freebsd-386) / [Linux](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-linux-386) / [Windows](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-windows-386.exe) ] * Architecture **amd64** [ [Darwin](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-darwin-amd64) / [FreeBSD](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-freebsd-amd64) / [Linux](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-linux-amd64) / [Windows](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-windows-amd64.exe) ] * Architecture **arm** [ [Linux](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-linux-arm) ] * Architecture **arm64** [ [Linux](https://github.com/ebrianne/adguard-exporter/releases/latest/download/adguard_exporter-linux-arm64) ] ### 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 get -u github.com/ebrianne/adguard-exporter # or $ git clone https://github.com/ebrianne/adguard-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 adguard_exporter . ``` ## Using Docker The exporter has been made available as a docker image. You can simply run it by the following command and pass the configuration with environment variables: ```bash docker run \ -e 'adguard_protocol=http' \ -e 'adguard_hostname=192.168.10.252' \ -e 'adguard_username=admin' \ -e 'adguard_password=mypassword' \ -e 'adguard_port=' \ #optional if adguard is not using port 80 (http)/443 (https) -e 'interval=10s' \ -e 'log_limit=10000' \ -e 'server_port=9617' \ -p 9617:9617 \ ebrianne/adguard-exporter:latest ``` If you prefer you can use an .env file where the environment variables are defined and using the command: ```bash docker run --env-file=.env -p 9617:9617 \ ebrianne/adguard-exporter:latest ``` You can also use docker-compose passing the environment file or using secrets locally ### Local with environment file ```yml version: "3.7" services: adguard_exporter: image: ebrianne/adguard-exporter:latest restart: always ports: - "9617:9617" env_file: - .env ``` ### Local with secret file (compose version 3 minimum) ```yml version: "3.7" secrets: my-adguard-pass: file: ./my-adguard-pass.txt services: adguard_exporter: image: ebrianne/adguard-exporter:latest restart: always secrets: - my-adguard-pass ports: - "9617:9617" environment: - adguard_protocol=http - adguard_hostname=192.168.10.252 - adguard_username=admin - adguard_password=/run/secrets/my-adguard-pass - adguard_port= #optional - interval=10s - log_limit=10000 ``` ### Swarm mode (docker swarm init) ```bash echo "mypassword" | docker secret create my-adguard-pass - ``` Here is an example of docker-compose file. ```yml version: "3.7" secrets: my-adguard-pass: external: true services: adguard_exporter: image: ebrianne/adguard-exporter:latest restart: always secrets: - my-adguard-pass ports: - "9617:9617" environment: - adguard_protocol=http - adguard_hostname=192.168.10.252 - adguard_username=admin - adguard_password=/run/secrets/my-adguard-pass - adguard_port= #optional - interval=10s - log_limit=10000 ``` ## Usage In order to run the exporter, type the following command (arguments are optional): Using a password ```bash $ ./adguard_exporter -adguard_protocol https -adguard_hostname 192.168.10.252 -adguard_username admin -adguard_password qwerty -log_limit 10000 ``` ```bash 2020/11/04 17:16:14 --------------------------------------- 2020/11/04 17:16:14 -

job_name: 'adguard' static_configs: - targets: ['localhost:9617'] ``` ## Available CLI options ```bash # Interval of time the exporter will fetch data from Adguard -interval duration (optional) (default 10s) # Protocol to use to query Adguard -adguard_protocol string (optional: "http", "https") (default "http") # Hostname of the Raspberry PI where Adguard is installed -adguard_hostname string (optional) (default "127.0.0.1") # Username to login to Adguard Home -adguard_username string (optional) # Password defined on the Adguard interface -adguard_password string (optional) # Port to use to communicate with Adguard API -adguard_port string (optional) # Limit for the return log data -log_limit string (optional) (default "1000") # Port to be used for the exporter -server_port string (optional) (default "9617") ``` ## Available Prometheus metrics | Metric name | Description | |:---------------------------------:|----------------------------------------------------------------------| | adguard_avg_processing_time | This represent the average DNS query processing time | | adguard_num_blocked_filtering | This represent the number of blocked DNS queries | | adguard_num_dns_queries | This represent the number of DNS queries | | adguard_num_replaced_parental | This represent the number of blocked DNS queries (parental) | | adguard_num_replaced_safebrowsing | This represent the number of blocked DNS queries (safe browsing) | | adguard_num_replaced_safesearch | This represent the number of blocked DNS queries (safe search) | | adguard_top_blocked_domains | This represent the top blocked domains | | adguard_top_clients | This represent the top clients | | adguard_top_queried_domains | This represent the top domains that are queried | | adguard_query_types | This represent the types of DNS queries | | running | Is Adguard running? | | protection_enabled | Is the protection enabled? | ## Systemd file ### Ubuntu One can enable the program to work at startup by writing a systemd file. You can put this file in /etc/systemd/system/adguard-home.service ``` [Unit] Description=AdGuard-Exporter After=syslog.target network-online.target Requires=AdGuardHome.Service [Service] ExecStart=/opt/adguard_exporter/adguard_exporter-linux-arm -adguard_protocol http -adguard_hostname -adguard_username -adguard_password -log_limit 5000 Restart=on-failure RestartSec=10s [Install] WantedBy=multi-user.target ``` Then do this command to start the service: ``` $ sudo systemctl start adguard-home.service ``` To enable the service at startup: ``` $ sudo systemctl enable adguard-home.service ```
