What Is a Spring Boot Actuator?

The Spring Boot Actuator is an effective tool for monitoring and managing a Spring Boot application and it provides a number of endpoints for that purpose, including health checks, metrics, configuration data, and trace data.

The Actuator endpoints offer a wide range of information on the functionality, configuration, and state of the application and may be accessed by HTTP or JMX. Utilizing this data will allow you to keep an eye on the program, identify problems, and decide how best to optimize and enhance it. This tool offers a variety of additional capabilities in addition to the usual endpoints, like auditing, caching, and security. These features make it easy to build a secure, scalable, and highly available application with Spring Boot.
