| == Usage |
| |
| You can register health checks for your applications with the https://camel.apache.org/manual/latest/health-check.html[Camel health check API]. |
| |
| By default, classes extending `AbstractHealthCheck` are registered as both liveness and readiness checks. For finer control over whether |
| a check is registered as a liveness or readiness check, you can extend either `AbstractCamelMicroProfileLivenessCheck` or `AbstractCamelMicroProfileReadinessCheck`. |
| |
| Any checks provided by your application are automatically discovered and bound to the Camel registry. They will be available via |
| the Quarkus health endpoints `/health/live` and `/health/ready`. |
| |
| You can also provide custom `HealthCheckRepository` implementations and these are also automatically discovered and bound to the Camel registry for you. |
| |
| Refer to the https://quarkus.io/guides/health-guide[Quarkus health guide] for further information. |
| |
