Production-ready Features

The spring-boot-actuator module provides all of Spring Boot’s production-ready features.

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
</dependencies>

Endpoints

Actuator endpoints let you monitor and interact with your application. Spring Boot includes a number of built-in endpoints and lets you add your own. For example, the health endpoint provides basic application health information.

Monitoring and Management Over HTTP

If you are developing a web application, Spring Boot Actuator auto-configures all enabled endpoints to be exposed over HTTP. The default convention is to use the id of the endpoint with a prefix of /actuator as the URL path. For example, health is exposed as /actuator/health.

Loggers

DEBUG

FATAL

Deploying Spring Boot Applications

You can deploy Spring Boot applications to a variety of cloud platforms, to virtual/real machines, or make them fully executable for Unix systems.

Kubernetes

Spring Boot auto-detects Kubernetes deployment environments by checking the environment for "*_SERVICE_HOST" and "*_SERVICE_PORT" variables. You can override this detection with the spring.main.cloud-platform configuration property.
