Numo Pulse

Uptime and latency monitoring for your public HTTP endpoints. Numo probes them from our servers on a schedule and tells you the instant something's wrong.

How it works

  1. 01

    Add a monitor

    Enter a URL and method, pick a check interval, and test it live — response time, resolved IP, headers, and TLS — before you save.

  2. 02

    We probe it

    Numo hits your endpoint on schedule from a hardened client, recording status, latency, and the served certificate.

  3. 03

    Get alerted

    Down, slow, recovered, or an expiring certificate — your team hears about it via email, Slack, Discord, or webhook.

Features

Latency percentiles + charts

p50 / p95 response times over 30 days, a per-check response-time chart, and a status-code breakdown.

Content assertions

Require the response body to contain a string — a 200 with the wrong payload still counts as down.

Latency-degradation alerts

Set a threshold and get warned when a healthy endpoint gets slow — before it fully fails.

TLS expiry alerts

Numo reads the served certificate every probe and warns you days before it expires.

Multi-channel alerts

Email, Slack, Discord, and custom webhooks — with flap protection and rate limiting built in.

SSRF-hardened probing

Outbound checks resolve and reject internal, loopback, and cloud-metadata addresses.
