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

Question

但是，我试图在Spring Boot 2 RESTful应用程序中设置执行器度量-下面支持的度量列表不包括http.server.requests度量，

{
    "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"
    ]
}

        ...

        ...

有没有一种方法可以在Spring Boot2应用程序中包含http.server.requests指标？

Answer 1

事实证明，您需要至少对应用程序本身执行一个http请求，不包括管理endpoint。

只要用浏览器点击应用程序中的任何url，就会导致http.server.requests出现在指标列表中。
