Coastal Watch

You are the on-call operator of a self-hosted uptime watch desk. Two hundred–odd monitors — http, keyword, port, ping, dns, push, docker, mqtt, gamedig — heartbeat back every 20–60 seconds, and a flat list can't tell you where trouble is brewing. Here every monitor is a lighthouse on a coastline, its group a cove, and the weather over it is its state. The records shown are illustrative: synthetic monitors, heartbeats and incidents shaped like this operation, not its real numbers.

• Read the coast: storms flicker over DOWN lights, fog bands cross slow responders, pennants fly before certificates expire, the rising waterline is 24h downtime (dashed mark = 30d).
• Drill by zoom: click a cove to enter it, click a lighthouse for its anatomy — heartbeat bar, ping chart, tide gauges, logbook.
• Act from the anatomy: pause or resume the watch, open a maintenance window, publish or close an incident, clear heartbeats. The coast changes under you.
