Just creating the working application and sharing standardized API documentation is not everything, especially if we are talking about microservices, where there are plenty of independent entities structuring one managed environment. The next important thing that needs to be mentioned is monitoring and gathering metrics from applications. In that aspect, Spring Boot also comes through. Project Spring Boot Actuator provides a number of built-in endpoints, which allow us to monitor and interact with the application. To enable it in our project, we should include spring-boot-starter-actuator in the dependencies. Here's a list of the most important Actuator endpoints:
Path | Description |
| Displays a full list of all the Spring beans initialized in the application. |
| Exposes properties from Spring’s Configurable Environment, which means, for example, OS environment variables and properties from configuration files. |
| Shows application health information. |
