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 收集器演示。

所以我复制了这四个配置文件

  • docker-compose.yml （在我的应用程序中，我删除了当前运行有问题的生成器部分和普罗米修斯）
  • otel-agent-config.yaml
  • otel-collector-config.yaml
  • .env

到我的应用程序。

同样基于 open-telemetry/opentelemetry-js repo 中的这两个演示：

我想出了我的版本（抱歉有点长，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=

码头工人-compose.yml

    metrics:
      receivers: [opencensus]
      processors: [batch]
      exporters: [logging]

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

我ConsoleSpanExporter在 Web 客户端和 Express.js 服务器中都工作。

但是，我在客户端和服务器中都尝试了这个 OpenTelemetry 导出器代码，我仍然无法连接 OpenTelemetry 收集器。

请参阅我对代码中 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', // No response, not exists.
    })
  )
);

任何的想法？谢谢

您尝试的演示使用的是旧配置和 opencensus，应将其替换为 otlp 接收器。话虽如此，这是一个工作示例 https://github.com/open-telemetry/opentelemetry-js/tree/master/examples/collector-exporter-node/docker 所以我从那里复制文件：

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"

收集器-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]

普罗米修斯.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']

这应该适用于 opentelemetry-js 版本。0.10.2

跟踪的默认端口是 55680，指标的默认端口是 55681

我之前发布的链接 - 您将始终在那里找到最新的工作示例： https ://github.com/open-telemetry/opentelemetry-js/tree/master/examples/collector-exporter-node 以及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。

因为我对与 Jaeger 集成更感兴趣。所以这里是设置所有 Jaeger、Zipkin、Prometheus 的配置。现在它适用于前端和后端。

首先前端和后端都使用相同的导出器代码：

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

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

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:
      - jaeger-all-in-one
      - zipkin-all-in-one

  # Jaeger
  jaeger-all-in-one:
    image: jaegertracing/all-in-one:latest
    ports:
      - "16686:16686"
      - "14268"
      - "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:
      - "9090:9090"

收集器-config.yaml

receivers:
  otlp:
    protocols:
      grpc:
      http:

exporters:
  jaeger:
    endpoint: jaeger-all-in-one:14250
    insecure: true
  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]

普罗米修斯.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']
