Gatus Health and Uptime Monitoring Dashboard by cloudimg

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Gatus is an automated health and uptime monitoring dashboard and status page. You describe the services you want to watch as a short list of endpoints in a single YAML file, each with its own check interval and success conditions, and Gatus continuously probes them and renders a clear, real time status page that shows what is up, what is down and how each service has behaved over time. Conditions are expressive: you can assert on HTTP status, response time, response body, DNS answers, TLS certificate expiry and more, across HTTP, TCP, ICMP, DNS and other protocols. Because the whole configuration is one declarative file, your monitoring is easy to version control and reproduce.

This image delivers Gatus fully installed and reverse proxied behind nginx, so a working status page is running within minutes of launch, with no manual package installation, no dependency troubleshooting and no proxy configuration required. It ships as a single self contained binary with an embedded SQLite backend, so it stays lightweight and starts instantly, and systemd manages the service for automatic restarts and clean logging.

Unlike a bare deployment, the image is configured to be secure by default. Gatus binds only to loopback and is served through an nginx reverse proxy that is ready for your TLS certificate. The status dashboard is read only by design, so there is no web admin surface, no login to manage and no default password or credential baked into the image. The Prometheus metrics endpoint is disabled so nothing beyond the intended dashboard and JSON API is exposed. A sensible default configuration monitors the instance's own web server and a couple of well known public endpoints, so the dashboard is populated on first boot and you can immediately replace the examples with your own services.

Features include a declarative YAML configuration, a live auto refreshing status page, a JSON API for programmatic access to endpoint statuses, per endpoint uptime history and response time tracking, TLS certificate expiry monitoring, and support for HTTP, TCP, ICMP, DNS, STARTTLS and other check types. An optional viewer password can be enabled by adding a basic authentication block to the configuration, generated uniquely on the machine and never baked into the image.
