title: Spring Boot Actuator and Log4j2
body: <p>In a Spring-Application I am trying to use Log4j2 instead of the default logging implementation Logback. So in my pom.xml I excluded <code>spring-boot-starter-logging</code> and included <code>spring-boot-starter-log4j2</code>. So I am able to use Log4j2.</p>
  
  <p>But if I open now the Spring Boot Acuator endpoint <code>localhost:8080/actuator/loggers</code> I am not seeing all Loggers anymore. With Logback there were several hundred Loggers but with Log4j2 I am seeing only about 10.</p>
  
  <p>My question is: How can I see the full list of all Loggers while using Log4j2 and not Logback in a Spring-Boot-Application?</p>
  
  <p>Edit:
  here is my pom.xml</p>
