Actuator exposes a number of endpoints exposing a lot of data. To be able to visualize the information better, we will add a HAL browser to our application:

 <dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-rest-hal-browser</artifactId>
 </dependency>

Spring Boot Actuator exposes REST APIs around all the data that's captured from the Spring Boot application and environment. The HAL BROWSER enables visual representations around the Spring Boot Actuator API:

You can launch HAL BROWSER by using the http://localhost:8080/ URL. You will see a screen similar to the following:

We can start browsing the Actuator API by typing in the URI for the actuator (/actuator) in the explorer and clicking Go. A screenshot of the screen is shown here:

Now, let's browse all the information that's exposed by the actuator as part of different endpoints through the HAL browser.
