Question

每个文档我都按照以下步骤操作，但是以某种方式，spring flow用户界面不显示指标。

第1步：启动Metric Server（kafka_2.11-0.11.0.2在端口9098上运行-由于默认端口上部署了其他一些应用程序，因此该端口不能保持默认值）

nohup ./bin/dataflow-server-metrics-collector-kafka-10 >/data/metrics.out &

上面的shell脚本是SCDF纱线的一部分，指向metrics-collector-kafka-10-1.0.0.RELEASE，在/config/collectors.yml中具有以下配置

server:
  port: 8081
security:
  basic:
    enabled: false
spring:
  cloud:
    stream:
      bindings:
        input:
          destination: metrics
      default:
        contentType: application/json

步骤2：我使用以下语句启动了SCDF服务器，该语句指向度量收集器的本地URI；由于上述yml中的安全性已禁用，因此在启动SCDF时不必费心提供用户名/ pwd

nohup ./bin/dataflow-server-yarn --spring.cloud.dataflow.metrics.collector.uri=http://10.73.122.131:8081  > /data/scdf.out &

第3步：我创建了一个流并将其部署到我们的Yarn群集中。部署时，我使用了以下命令：

stream deploy --name pmmlTest --properties "app.*.spring.cloud.stream.bindings.applicationMetrics.destination=metrics"

现在，当我期望Flo UI显示计数器时，将显示SCDF日志： 'Failure while requesting metrics from url http://10.73.122.131:8081/collector/metrics/streams': I/O error on GET request for "http://10.73.122.131:8081/collector/metrics/streams": Connection refused

我相信的原因是，指标收集器始终将bootstrap.servers用作kafka代理绑定的localhost：9092，而不是localhost：9098 。

我试图在/Config/Collectors.yml中添加以下行，但结果相同。

kafka:
  consumer:
    bootstrap: localhost:9098

不确定如何正确告诉指标收集器使用9098而不是9092。这是Metrics Collector的启动日志：

无法将Metrics Collector与Kafka一起使用Spring Cloud Dataflow
