UPTIME MONITORING GUIDE

API Health Check Monitoring Best Practices

A useful health endpoint should be inexpensive, safe, and representative of the service customers need. A check that always returns success can hide dependency failures.

Choose readiness over process health

A running process is not necessarily ready to serve traffic. When appropriate, a readiness endpoint should reflect required dependencies such as databases or queues.

Avoid side effects

Monitoring runs repeatedly. Use GET or HEAD endpoints that do not send messages, create records, consume inventory, or trigger expensive work.

Separate critical surfaces

Monitor major APIs independently when they can fail in different ways. This improves alert clarity and makes a status page more informative.

Key takeaways

  • Check meaningful readiness.
  • Keep the endpoint safe and lightweight.
  • Monitor independently failing services separately.
