Can Gatus monitor services on a private network?
Yes. Endpoints can be any URL, hostname, IP or port the container can reach, so a NAS, reverse proxy or app behind a VPN works without a public address.
Gatus: Self-Hosted Health Dashboard
Check whether the services in your homelab are answering, and get told when one stops. Gatus runs HTTP, ping, TCP and DNS checks on a schedule, plus certificate expiry, and puts the results on a dashboard. The whole setup lives in one config file you edit.

Common questions
Where does Gatus keep its check history?
In memory by default, which means a restart clears it. Set storage to SQLite or Postgres to keep uptime and response time history across restarts.
How does Gatus send an alert?
Each endpoint carries its own alert list for ntfy, Gotify, Slack, Discord, Telegram, email, PagerDuty and others. An alert fires once the failure threshold you set is reached, and a second message can follow when the endpoint recovers.
