spring 引導 2.7.0 不公開 http.server.request 指標

Question

我正在使用 Spring boot 2.7.0 並且我正在嘗試公開 http.server.request 指標，以便我可以在 Prometheus 中抓取它，但它不起作用。 我的 application.yml 屬性如下所示：

management:
    endpoint:
        health:
            probes:
                enabled: true
            show-details: always
    endpoints:
        web:
            exposure:
                include: '*'

    health:
        livenessState:
            enabled: true
        readinessState:
            enabled: true
    metrics:
        tags:
            application: ${spring.application.name}
        distribution:
            percentiles-histogram:
                http:
                    server:
                        requests: true

我有以下依賴項：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
    <scope>runtime</scope>
</dependency>

但在/actuator/metrics端點中，我看不到任何關於 http.server.request 指標的信息。

    "tomcat.sessions.alive.max",

    "tomcat.sessions.rejected"
  ]
}

我的隊友能夠通過將 spring 引導版本降級到 2.3.7.release 來解決這個問題，但我不太喜歡這個。 有沒有其他方法可以公開這些指標？

Answer 1

這是 2.7.0 spring 引導版本的問題。 升級到 2.7.1
