Relentless 5-minute probes

Every monitor is checked on a 5-minute cadence — or as fast as every minute. GET or HEAD, 10-second timeout, redirects followed.

Every response, logged

HTTP status, latency, and the exact failure cause for every probe. Seven days of history with live uptime percentages.

Your definition of healthy

Expect an exact HTTP status or enforce a maximum response time. Each monitor gets its own success rules without duplicate probes.
