Example using Spring Actuator

Spring Actuator enables the monitoring of Spring Boot applications. It enables the gathering of various application metrics, database status, and traffic details.

The main benefit of this library is that we can get production grade tools without having to actually implement these features ourselves.

Actuator is mainly used to expose operational information about the running application—health, metrics, info, dump, env, and so on. It uses HTTP endpoints or JMX beans to enable us to interact with it.

You enable Actuator by adding the Maven dependency, and several endpoints are enabled out of the box, which can be extended or customized as needed:

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