Spring Boot Actuator adds a number of health monitoring endpoints to support monitoring of your Spring Boot based applications. To add to an existing Spring Boot app, you just add a dependency on spring-boot-starter-actuator as described here.
This works out of the box for a Spring MVC based Spring Boot app, but if you’re building JAX-RS endpoints using Jersey, by default the Jersey resources and Actuator resources both get mapped to the root ( / ), so you need to map either Jersey or Actuator to something other than /. You can easily re-map Actuator be adding this line to application.properties (change /system as needed):
server.servlet-path=/system
