This is basically the only reason why I occasionally log in to Facebook these days. Facebook groups seems to be the place where car owners gather to share information regarding their vehicles, at least here in Finland. I have found discussions in these groups very valuable e.g. when I'm diagnosing a problem or evaluating whether some defect will be covered by warranty or not.
You need to include a separate actuators module to enable them. IIRC in Spring Boot version 1.5 and older actuators were enabled and exposed as web endpoints by default. The heapdump endpoint mentioned in the article also required inclusion of Spring MVC module – which I guess most web apps do include.
In Spring Boot 2.0 and newer actuator module only exposes "info" and "health" web endpoints by default. Default configuration does expose more endpoints via JMX, though. Also, if your project includes Spring Security module actuator endpoints are secured by default.
