Spring Actuator is a sub-project of the Spring Boot framework that provides production-ready features to help you monitor and manage your application easily. It offers various endpoints and tools to gather information about the application's health, metrics, environment, and other useful insights.
Step 1: Add Actuator Dependency
In your Spring Boot project's pom.xml (for Maven) or build.gradle (for Gradle), include the Spring Boot Actuator dependency:
Step 2: Configure Actuator Endpoints (Optional)
By default, most Actuator endpoints are enabled. However, you can customize the behavior and enable/disable specific endpoints in your application.properties or application.yml file:
# To enable all endpoints management.endpoints.web.exposure.include=*
# To enable all endpoints management: endpoints: web: exposure: include: '*'
Step 3: Access Actuator Endpoints
Once you've configured Actuator, you can access its endpoints using HTTP requests. The default base path for Actuator endpoints is /actuator. For example, to access the health endpoint, make a GET request to /actuator/health.
Here are a few examples of accessing different Actuator endpoints:
Remember that Actuator endpoints may expose sensitive information, so it's crucial to secure them properly in production environments
That's it! With these steps, you should have Spring Actuator up and running in your Spring Boot project, allowing you to monitor and manage your application with ease.
