如何在 Spring Boot 2x Actuator 中启用 Spring MVC 指标

Question

我正在尝试在 Spring Boot 2 RESTful 应用程序中设置执行器指标，但是 - 下面支持的指标列表不包括 http.server.requests 公制,

这是 Spring MVC 指标的一部分，如 https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#production-ready-metrics-spring-mvc

中所述

以下是返回的可用指标：

{
    "names": [
        "jvm.threads.states",
        "jvm.memory.used",
        "jvm.gc.memory.promoted",
        "jvm.memory.max",
        "jvm.gc.max.data.size",
        "jvm.memory.committed",
        "system.cpu.count",
        "logback.events",
        "tomcat.global.sent",
        "jvm.buffer.memory.used",
        "tomcat.sessions.created",
        "jvm.threads.daemon",
        "system.cpu.usage",
        "jvm.gc.memory.allocated",
        "tomcat.global.request.max",
        "tomcat.global.request",
        "tomcat.sessions.expired",
        "jvm.threads.live",
        "jvm.threads.peak",
        "tomcat.global.received",
        "process.uptime",
        "tomcat.sessions.rejected",
        "process.cpu.usage",
        "tomcat.threads.config.max",
        "jvm.classes.loaded",
        "jvm.classes.unloaded",
        "tomcat.global.error",
        "tomcat.sessions.active.current",
        "tomcat.sessions.alive.max",
        "jvm.gc.live.data.size",
        "tomcat.threads.current",
        "jvm.gc.pause",
        "jvm.buffer.count",
        "jvm.buffer.total.capacity",
        "tomcat.sessions.active.max",
        "tomcat.threads.busy",
        "process.start.time"
    ]
}

我已经包含了以下依赖项（其中包括）：

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

有没有办法在我的 Spring Boot 2 应用程序中包含 http.server.requests 指标？

Answer 1

事实证明 - 您需要对应用程序本身执行至少一个 http 请求 - 不包括管理端点。

只需在应用程序中使用浏览器点击任何 url，就会导致 http.server.requests 出现在指标列表中。
