What UpDownBoard actually looks like running on your network.

Dashboard

The main view. Each tile represents one monitored system — GREEN means all checks are passing, RED means something is broken. Tiles update automatically every 15 seconds.

All-clear detail

Green tiles show passing status too. CPU 42%, memory 61%, disk 38% — Linux Server is doing fine.

/status endpoint

Plain-text view of the current state and recent state-change history. Useful on a wall monitor with watch curl http://updownboard.local:8080/status, or piped into anything that reads text.

/api/systems endpoint

Raw JSON state for all systems. Wire it into your own dashboards, alerting pipelines, or whatever else you can think of. It's just an HTTP GET.
