Uptime monitoring

Numo Pulse probes your public HTTP endpoints on a schedule and alerts you when they go down, get slow, or their certificate is expiring.

1. Add a monitor

Open Numo Pulse and click Add monitor. Enter the URL and method (GET, POST, or HEAD), a check interval, and a timeout. Numo requires you to testthe endpoint first — you'll see the response time, resolved IP, headers, and TLS certificate before saving.

2. What counts as healthy

By default a monitor is up when it returns the expected status code (200 by default). Under Advanced checks you can tighten that:

  • Content assertion — require the response body to contain a string. A 200 with the wrong payload is marked down.
  • Latency threshold — get a slowalert when a healthy response is slower than your threshold, and a recovery when it's back under.
  • TLS expiry— Numo reads the served certificate every probe and warns you when it's within your chosen number of days of expiring.

3. Alerts

Down, recovered, slow, latency-recovered, and TLS-expiring events are delivered to your workspace's alert channels — the same email, Slack, Discord, and webhook channels Beat uses. See Alert channels to connect one. Snooze a monitor during known work to mute it temporarily.

Tip:the monitor detail page shows p50/p95 latency, a response-time chart, status-code distribution, and the incident & alert history for that endpoint.
