prometheus - 使用 Actuator 未在 http 端点上公开 kafka 生产者指标

Question

我正在使用 Spring boot 2、Kafka 2.1.4，并且我想在 spring boot actuator 的 actuator/metrics 端点中公开 kafka Producer 指标

pom.xml

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

在我的属性文件中看起来像这样 #application.properties

    management.endpoints.web.exposure.include=*
    management.endpoint.health.show-details=always
    management.endpoint.metrics.enabled=true
    management.endpoint.prometheus.enabled=true
    management.metrics.export.prometheus.enabled=true

结果没有kafka生产者指标只有Jvm和Tomcat

http://localhost:8080/actuator/metrics
