Spring Cloud Data Flow Grafana Prometheus未显示流数据 [英] Spring Cloud Data Flow Grafana Prometheus not showing stream data

问题描述

我在此网站上使用docker-compose启动Spring云数据流.

问题1:流的状态始终为正在部署".不应该部署它吗?

问题2:

当我单击"Grafana"图标时，它会启动Grafana页面，但上面没有数据.为什么会这样呢?我将kafka用作消息传递中间件，如下所示.

 < dependency>< groupId> org.springframework.cloud</groupId>< artifactId> spring-cloud-stream-binder-kafka</artifactId></dependency> 

这是我的pom.xml

解决方案

我解决了这个问题，在属性中添加了一些依赖项和一些条目.

pom.xml:

 < dependency>< groupId> org.springframework.boot</groupId>< artifactId> spring-boot-starter-web</artifactId></dependency><依赖关系>< groupId> org.springframework.boot</groupId>< artifactId> spring-boot-starter-webflux</artifactId></dependency><依赖关系>< groupId> org.springframework.boot</groupId>< artifactId> spring-boot-starter-actuator</artifactId></dependency><依赖关系>< groupId> org.springframework.cloud.stream.app</groupId>< artifactId> app-starters-micrometer-common</artifactId>< version> 2.1.2.RELEASE</version></dependency><依赖关系>< groupId> io.micrometer</groupId>< artifactId>千分尺普罗米修斯< artifactId></dependency><依赖关系>< groupId> io.micrometer.prometheus</groupId>< artifactId>普罗米修斯·索克·斯普林斯</artifactId>< version> 0.9.0</version></dependency> 

application.properties:

  spring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.enabled = truespring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.rsocket.enabled = truespring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.rsocket.host = prometheus-rsocket-proxyspring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.rsocket.port = 7001spring.cloud.dataflow.applicationProperties.stream.management.endpoint.health.show-details = alwaysspring.cloud.dataflow.applicationProperties.stream.management.endpoint.health.show-components = alwaysspring.cloud.dataflow.applicationProperties.stream.management.endpoints.jmx.exposure.include = *spring.cloud.dataflow.applicationProperties.stream.management.endpoints.web.exposure.include = * 

I launch Spring cloud data flow with docker-compose base on this website.

https://dataflow.spring.io/docs/installation/local/docker/

I created 3 apps, Source, Processor & Sink.

I ran

export STREAM_APPS_URI=https://dataflow.spring.io/Einstein-BUILD-SNAPSHOT-stream-applications-kafka-maven

When I run docker-compose -f ./docker-compose.yml -f ./docker-compose-prometheus.yml up, all my containers start up as specified in the docker-compose.yml and docker-compose-prometheus.yml.

I proceed to register the 3 applications and then create a stream with them.I then run it.

Question 1: The status of the stream is always "Deploying". Shouldn't it be Deployed?

Question 2:

When I click on the "Grafana" icon, it launches the Grafana page but there is no data on it. Why is it so? I am using kafka as my messaging middleware as shown below.

解决方案

I solved this issue adding some dependencies and some entries on properties.

pom.xml:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud.stream.app</groupId>
            <artifactId>app-starters-micrometer-common</artifactId>

        </dependency>
        <dependency>

        </dependency>
        <dependency>

            <artifactId>prometheus-rsocket-spring</artifactId>
            <version>0.9.0</version>
        </dependency>

application.properties:

spring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.enabled=true
spring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.rsocket.enabled=true
spring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.rsocket.host=prometheus-rsocket-proxy
