JavaSpring Boot Prometheus指标添加log4j2_events_total指标

Question

我为普罗米修斯和Actuator添加了依赖项：

<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-core</artifactId>
  <version>${micrometer-registry-prometheus.version}</version>
</dependency>
<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-registry-prometheus</artifactId>
  <version>${micrometer-registry-prometheus.version}</version>
</dependency>
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-actuator</artifactId>
  <exclusions>
    <exclusion>
      <artifactId>spring-boot-starter-logging</artifactId>
      <groupId>org.springframework.boot</groupId>
    </exclusion>
  </exclusions>
</dependency>

但是，如果我去endpoint /actuator/promehteuslog4j2_events_total指标是不到位的，即使我还添加了log4j2依赖从Spring Boot启动器，我错过了一些额外的配置吗？

试试这个，我创建了一个新项目，它在添加以下依赖项后为我工作。确保添加spring-boot-starter-web依赖项并从中排除spring-boot-starter-log以避免SLF4J：类路径包含多个SLF4J绑定。ERROR。
