Learn Java from Scratch - A Beginner's Guide - Step 09 - Exploring Spring Boot Actuator

The video tutorial introduces Spring Boot Actuator, a tool for monitoring and managing Spring Boot applications in production. It covers the integration of Actuator into a Spring Boot project, exploring its various endpoints for health checks, metrics, and request mappings. The tutorial also demonstrates how to configure Actuator endpoints through application properties and highlights the importance of enabling only necessary endpoints for security and performance.

What is one of the main purposes of Spring Boot Actuator?

• To enhance the user interface of applications
