AdGuard Metrics Statistics

AdGuard Exporter for Prometheus

A lightweight Prometheus exporter written in Go that exposes detailed metrics from your AdGuard Home instance — including DNS statistics, blocked domains, upstreams, and client data.

Prerequisites

Before running this exporter, make sure:

• AdGuard Home is up and running
• You have a valid AdGuard username & password
• Prometheus is configured to scrape this exporter
• Docker installed (or alternatively Go 1.20+ for building from source)
• Port 9600 is available on your system

To make sure the endpoint is valid, you can check the endpoints via curl
