# gatus # gatus
## Overview ## Overview
The gatus stack is a NetGrimoire service monitor that provides real-time status updates for the Gatus application. It consists of the Gatus service, which runs as a Docker container on docker4, and exposes its status via Caddy's reverse proxy. The gatus stack provides a service monitor for NetGrimoire, responsible for tracking the status of Gatus services.
