# Monitoring system health

Use the built-in HTTP API endpoints for health monitoring.

### Recommended endpoints

* Use [Health check](/v6.12.0/api-reference/auxiliary-api-commands/health-check.md) for uptime checks.
  * It’s the best signal for “is the service alive”.
  * It also validates the license.
* Use [Status API](/v6.12.0/api-reference/auxiliary-api-commands/status-api.md) for readiness checks.
  * It reports whether spell/grammar/AI engines are active.

### How to wire this into monitoring

1. Configure your monitoring system to send periodic `GET` requests.
2. Alert on non-`200` responses.
3. If your monitor supports it, also alert when `license.valid=false`.
