Knowledge base

Guides for setting up checks, understanding confirmation, wiring alerts, and running status pages.

Getting started

Accounts, checks, regions, and your first alert.

Check types

HTTP, TCP, DNS, SSL, domain, ping, and heartbeat checks.

  • HTTP checks Monitor a URL's status code, response body, and TLS certificate, with custom headers and basic auth.
  • TCP checks Confirm a host and port accept connections, optionally sending a probe string and matching the reply.
  • DNS checks Resolve A, AAAA, CNAME, MX, TXT, or NS records against a chosen resolver and optionally match expected values.
  • SSL certificate checks Track certificate validity and expiry separately from uptime, with warnings well before a certificate lapses.
  • Domain expiry checks Track a domain's registration expiry so a forgotten renewal never takes your site down without warning.
  • Ping checks ICMP echo checks with a configurable packet-loss threshold.
  • Heartbeat checks A dead-man's-switch URL your job calls in — miss the grace period and Status raises it.

Confirmation

How multi-region quorum stops false alerts.

Alerting

Email and webhook channels, thresholds, and signing.

Status pages

Public status pages, custom domains, and subscribers.

  • Create a status page Share a hosted public status page for the checks you choose, with an optional password gate and email subscribers.
  • Custom domains for status pages Point status.yourcompany.com at your Status page with a CNAME, then verify it for automatic TLS.

Maintenance

Suppress alerts during planned work.

  • Maintenance windows Schedule a window over one check, several, or your whole account so planned work doesn't page anyone.

Reports & badges

Uptime reports and embeddable badges.

  • Coming soon.

API

Keys, scopes, and the public v1 API.

  • API keys and scopes Manage checks, alert channels, and incidents from your own tooling with a scoped v1 API key.
