Monitoring and Managing Spring Boot Applications Using Actuator

Spring Boot Logo

Spring Boot is a powerful framework for building modern, cloud-native applications in Java. It provides a streamlined development experience and simplifies the process of creating stand-alone, production-grade Spring-based applications.

One important aspect of any application is the ability to monitor and manage its runtime behavior. Spring Boot comes with a built-in feature called Actuator that makes it easy to monitor and manage Spring Boot applications by providing several out-of-the-box production-ready endpoints.

What is Actuator?

Actuator is a module in Spring Boot that provides a set of RESTful endpoints for monitoring and managing a Spring Boot application. With Actuator, you can gather useful information about your application's internals, such as health, metrics, and more.

Actuator endpoints expose various management and monitoring features over HTTP or JMX. These endpoints are automatically enabled when you include Actuator in your application's classpath, and you can further configure them to suit your specific requirements.

Key Features of Actuator

Actuator provides a wide range of endpoints to monitor and manage your application. Some of the key features include:

  1. Health Endpoint: The health endpoint provides information about the health of the application. It can be used to determine if the application is running properly or not.

  2. Metrics Endpoint: The metrics endpoint exposes various useful metrics about your application, such as JVM memory usage, thread pools, database connections, and more. These metrics can help you monitor your application's performance and identify bottlenecks.

  3. Info Endpoint: The info endpoint allows you to provide custom information about your application, such as version, build date, and other relevant details.

  4. Logging Endpoint: The logging endpoint allows you to view and modify the logging configuration of your application at runtime. You can change the log levels, view log files, and even change the logging pattern.

  5. Auditing Endpoint: The auditing endpoint provides information about the recent actions performed on your application, such as HTTP requests, database updates, etc.

  6. Environment Endpoint: The environment endpoint provides information about the application's environment, such as system properties, application properties, etc.

  7. Shutdown Endpoint: The shutdown endpoint allows you to gracefully shut down your application. By default, this endpoint is not enabled for security reasons, but you can enable it if required.

Enabling Actuator in a Spring Boot Application

Enabling Actuator in a Spring Boot application is quite straightforward. You just need to include the Actuator starter dependency in your project's build file, such as pom.xml for Maven or build.gradle for Gradle.

For Maven:


For Gradle:

implementation 'org.springframework.boot:spring-boot-starter-actuator'

Once you have added the Actuator dependency, you can start your Spring Boot application, and Actuator endpoints will be automatically available at their respective URLs.

Customizing Actuator Endpoints

Actuator endpoints can be customized to suit your specific requirements. You can modify the base path, enable or disable specific endpoints, add custom metrics, and even secure the endpoints using Spring Security.

To customize Actuator endpoints, you can use the configuration properties provided by Spring Boot. These properties allow you to fine-tune various aspects of Actuator, such as endpoint paths, security settings, and more.

For example, to customize the base path of Actuator endpoints, you can add the following property to your file:


This will change the base path of all Actuator endpoints to /actuator, making them accessible at /actuator/health, /actuator/metrics, and so on.


Monitoring and managing Spring Boot applications is essential for maintaining their health and ensuring optimal performance. Actuator provides a convenient way to expose useful management and monitoring endpoints without much effort.

In this article, we explored the key features of Actuator and how to enable and customize its endpoints in a Spring Boot application. With Actuator, you can easily monitor your application's health, view important metrics, manage logging, and much more.

So, next time you develop a Spring Boot application, don't forget to include Actuator and leverage its powerful monitoring and management capabilities. Happy coding!
