如何在客户端和服务器中正确使用OpenTelemetry导出器和OpenTelemetry收集器？

如何解决如何在客户端和服务器中正确使用OpenTelemetry导出器和OpenTelemetry收集器？

我正在尝试使OpenTelemetry导出器与OpenTelemetry收集器一起使用。

我找到了这个OpenTelemetry collector demo。

所以我复制了这四个配置文件

• docker-compose.yml（在我的应用中，我删除了当前正在运行的问题的生成器部分和prometheus）
• otel-agent-config.yaml
• otel-collector-config.yaml
• .env

到我的应用。

还基于open-telemetry / opentelemetry-js存储库中的这两个演示：

• Traces in Web demo
• Traces in Node - GRPC demo

我想出了我的版本（很抱歉，由于缺少文档，很难设置最低工作版本）：

.env

OTELCOL_IMG=otel/opentelemetry-collector-dev:latest
OTELCOL_ARGS=

docker-compose.yml

version: '3.7'
services:

运行docker-compose up -d后，我可以打开Jaeger（http：// localhost：16686）和Zipkin UI（http：// localhost：9411）。

我的ConsoleSpanExporter在Web客户端和Express.js服务器中均可工作。

但是，我在客户端和服务器上都尝试过此OpenTelemetry导出程序代码，但在连接OpenTelemetry收集器时仍然遇到问题。

请在代码中查看我对URL的评论

import { CollectorTraceExporter } from '@opentelemetry/exporter-collector';

// ...
tracerProvider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
tracerProvider.addSpanProcessor(
  new SimpleSpanProcessor(
    new CollectorTraceExporter({
      serviceName: 'my-service',// url: 'http://localhost:55680/v1/trace',// Return error 404.
      // url: 'http://localhost:55681/v1/trace',// No response,not exists.
      // url: 'http://localhost:14268/v1/trace',not exists.
    })
  )
);

有什么主意吗？谢谢

解决方法

您尝试的演示使用的是较早的配置和opencensus，应将其替换为otlp接收器。话虽如此，这是一个可行的例子 https://github.com/open-telemetry/opentelemetry-js/tree/master/examples/collector-exporter-node/docker 所以我要从那里复制文件：

docker-compose.yaml

version: "3"
services:
  # Collector
  collector:
    image: otel/opentelemetry-collector:latest
    command: ["--config=/conf/collector-config.yaml","--log-level=DEBUG"]
    volumes:
      - ./collector-config.yaml:/conf/collector-config.yaml
    ports:
      - "9464:9464"
      - "55680:55680"
      - "55681:55681"
    depends_on:
      - zipkin-all-in-one

  # Zipkin
  zipkin-all-in-one:
    image: openzipkin/zipkin:latest
    ports:
      - "9411:9411"

  # Prometheus
  prometheus:
    container_name: prometheus
    image: prom/prometheus:latest
    volumes:
      - ./prometheus.yaml:/etc/prometheus/prometheus.yml
    ports:
      - "9090:9090"

collector-config.yaml

receivers:
  otlp:
    protocols:
      grpc:
      http:

exporters:
  zipkin:
    endpoint: "http://zipkin-all-in-one:9411/api/v2/spans"
  prometheus:
    endpoint: "0.0.0.0:9464"

processors:
  batch:
  queued_retry:

service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: [zipkin]
      processors: [batch,queued_retry]
    metrics:
      receivers: [otlp]
      exporters: [prometheus]
      processors: [batch,queued_retry]

prometheus.yaml

global:
  scrape_interval: 15s # Default is every 1 minute.

scrape_configs:
  - job_name: 'collector'
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
      - targets: ['collector:9464']

这在opentelemetry-js ver中应该可以正常工作。 0.10.2

跟踪的默认端口为55680，度量标准的默认端口为55681

我之前发布的链接-您将始终在这里找到最新的工作示例： https://github.com/open-telemetry/opentelemetry-js/tree/master/examples/collector-exporter-node 对于网络示例，您可以使用相同的docker并在此处查看所有工作示例： https://github.com/open-telemetry/opentelemetry-js/tree/master/examples/tracer-web/

非常感谢@BObecny的帮助！这是@BObecny答案的补充。

由于我对与Jaeger集成更感兴趣。因此，这是与所有Jaeger，Zipkin，Prometheus一起设置的配置。现在它既可以在前端也可以在后端使用。

首先，前端和后端都使用相同的导出程序代码：

import { CollectorTraceExporter } from '@opentelemetry/exporter-collector';

new SimpleSpanProcessor(
  new CollectorTraceExporter({
    serviceName: 'my-service',})
)

docker-compose.yaml

    ports:
      - "9464:9464"
      - "55680:55680"
      - "55681:55681"
    depends_on:
      - jaeger-all-in-one
      - zipkin-all-in-one

  # Jaeger
  jaeger-all-in-one:

      - "14250"

  # Zipkin
  zipkin-all-in-one:
    image: openzipkin/zipkin:latest
    ports:
      - "9411:9411"

  # Prometheus
  prometheus:
    container_name: prometheus
    image: prom/prometheus:latest
    volumes:
      - ./prometheus.yaml:/etc/prometheus/prometheus.yml
    ports:
