Spring Cloud Dataflow 自定义流应用程序指标未显示在 Grafana 中

Question

SCDF 版本 2.10.2

我无法让我的自定义源、处理器或接收器向我的 prometheus/grafana 设置公开指标。

---

我在这里遵循了自定义流应用程序教程：https://dataflow.spring.io/docs/stream-developer-guides/streams/standalone-stream-sample/

我找到了各种来源，了解我需要向我的应用程序添加哪些依赖项才能让它们在我的 grafana/prometheus 设置中进行跟踪，但似乎没有任何效果。如果我在流中使用来自 dataflow.spring.io 的示例应用程序，那么我会得到流向 grafana 的指标。

至少看起来我需要这种依赖：

<dependency>
    <groupId>org.springframework.cloud.stream.app</groupId>
    <artifactId>app-starters-micrometer-common</artifactId>
    <version>2.1.5.RELEASE</version>
</dependency>

那似乎没有做任何事。

我看到一些其他的 stackoverflow 答案建议添加这些依赖项：

<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>
<dependency>
    <groupId>io.micrometer.prometheus</groupId>
    <artifactId>prometheus-rsocket-spring</artifactId>
    <version>0.9.0</version>
</dependency>

那些似乎也不起作用并导致 NoClassDefFound: io.rsocket.AbstractRSocket 异常。
