Fullstack Java: Introduction to Spring Boot Actuator for Monitoring Applications

In fullstack Java development, monitoring application health and performance is critical—especially in production environments. Whether you're building REST APIs, microservices, or complex web apps, having real-time insights into your Spring Boot application can help identify issues before they affect users. This is where Spring Boot Actuator becomes invaluable.

Spring Boot Actuator is a powerful module that provides built-in endpoints to help developers monitor and manage applications with minimal setup. In this blog, we’ll explore what Spring Boot Actuator is, how to set it up, and the key features it offers for effective application monitoring.


What is Spring Boot Actuator?

Spring Boot Actuator adds production-ready features to your application. It exposes a number of built-in HTTP endpoints that allow you to monitor and interact with your app—such as checking application health, viewing metrics, inspecting beans, and more. These endpoints can be accessed via HTTP, JMX, or even integrated into cloud monitoring tools like Prometheus and Grafana.


Setting Up Spring Boot Actuator

Getting started is easy. Simply add the following dependency to your pom.xml if you’re using Maven:

xml


<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-actuator</artifactId>

</dependency>

For Gradle users:

groovy

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

Once added, Spring Boot automatically enables some default endpoints such as /actuator/health and /actuator/info.


Common Actuator Endpoints

Here are some of the most commonly used Actuator endpoints:

  • /actuator/health: Returns the health status of the application (e.g., UP, DOWN).
  • /actuator/info: Displays custom application information (configured in application.properties).
  • /actuator/metrics: Exposes metrics related to memory, CPU, garbage collection, and more.
  • /actuator/env: Shows environment properties and configuration values.
  • /actuator/beans: Lists all Spring beans and their dependencies.
  • /actuator/httptrace: Displays the last few HTTP requests handled by the app.

You can enable or disable specific endpoints in your application.properties file:


properties

management.endpoints.web.exposure.include=health,info,metrics

To expose all endpoints (for development purposes only):


properties

Copy

Edit

management.endpoints.web.exposure.include=*


Customizing Health Checks and Info

You can create custom health indicators by implementing the HealthIndicator interface:


java

@Component

public class CustomHealthIndicator implements HealthIndicator {

    @Override

    public Health health() {

        return Health.up().withDetail("customStatus", "Available").build();

    }

}

You can also add build or application info:


properties

info.app.name=My Spring Boot App

info.app.version=1.0.0

This information will be available at /actuator/info.


Integration with Monitoring Tools

Spring Boot Actuator integrates well with Prometheus, Micrometer, and other monitoring systems. Micrometer, the metrics collection facade used by Spring Boot, lets you push metrics to tools like:

  • Prometheus
  • New Relic
  • Datadog
  • Elastic Stack

This allows you to visualize trends, set up alerts, and monitor performance over time.


Final Thoughts

Spring Boot Actuator is a must-have for fullstack Java developers who want to build resilient, observable, and production-ready applications. With minimal configuration, you gain deep visibility into your application’s health and behavior. Whether you’re deploying a small API or a complex microservice architecture, Actuator equips you with the tools to keep your application running smoothly.

How to Use Tosca's Test Configuration Parameters

Tosca by Tricentis is a powerful model-based test automation tool widely used in enterprise environments for end-to-end testing. One of its most useful features is Test Configuration Parameters (TCPs), which provide flexibility and control in managing test execution. TCPs enable testers to create reusable test cases by passing dynamic values without hardcoding them. This significantly enhances test maintenance, scalability, and efficiency. In this blog, we’ll explore what Test Configuration Parameters are, how to create and use them, and the best practices to follow when working with TCPs in Tosca. What Are Test Configuration Parameters? Test Configuration Parameters are custom-defined key-value pairs that can be associated with test cases, test case folders, or execution lists in Tosca. They help manage configuration data such as environment URLs, browser types, credentials, or any other variable data that may differ across test runs. By using TCPs, you can avoid duplicating test case...

Using Hibernate ORM for Fullstack Java Data Management

In the world of fullstack Java development, managing data efficiently and seamlessly across the application is critical. One of the most powerful tools in the Java ecosystem for handling database operations is Hibernate ORM (Object-Relational Mapping). Hibernate simplifies the interaction between Java applications and relational databases, reducing boilerplate code and improving maintainability. This blog explores how Hibernate ORM works, why it’s widely used, and how it fits into the data management strategy of a fullstack Java application. What is Hibernate ORM? Hibernate ORM is an open-source Java framework that provides a powerful and flexible mechanism for mapping Java objects to database tables. It abstracts the low-level JDBC code, allowing developers to work with high-level object-oriented concepts. Instead of writing raw SQL queries, Hibernate allows developers to define database interactions using simple Java classes (also known as POJOs) and annotations or XML configurations...
