Website Monitoring Checklist
A practical checklist for website, network, certificate, domain and scheduled-job reliability.

Before relying on monitoring
List the services customers actually use: public pages, essential APIs, mail-related domains and infrastructure endpoints. Name each monitor so someone outside the engineering team understands its purpose. Start with the most important service, inspect a real result, then expand coverage where it answers a concrete operational question.
Availability and network
Check the canonical HTTPS page, expected status and a stable content marker. Add API assertions for critical machine-facing endpoints. Use Ping and TCP to diagnose public-host reachability and port acceptance, remembering that a reachable host is not proof of application correctness. Confirm that every target is yours or that you have permission to monitor it.
Expiry and background work
Track certificates and domain registrations separately. Identify who can renew each one and verify warnings reach them. Add a heartbeat for backups, scheduled exports and billing jobs. A heartbeat must follow actual success; keep restoration and data-integrity checks in your own operating process.
People and communication
Assign at least two owners when your team structure permits. Give routine operators member access and observers viewer access. Test notification channels, document who responds, and use planned maintenance windows. Publish only safe component names on status pages and distinguish manual investigation updates from actual monitor state.
Review after setup and change
Inspect weekly/monthly summaries, long incidents and slow endpoints. Confirm history coverage before comparing percentages. After deployments, domain migrations, certificate renewal or staff changes, verify the relevant monitors and recipients again. Review stale credentials, invitations and API tokens. A checklist is useful only when its results are revisited.
Common questions
How many monitors should I start with?
Start with the most important customer-facing service and add checks for distinct failure modes.
How often should I review settings?
Review after meaningful infrastructure or team changes, and during your regular operational review.
