I am trying to make OpenTelemetry exporter to work with OpenTelemetry collector.

I found this OpenTelemetry collector demo.

So I copied these four config files

• docker-compose.yml (In my app, I removed generators part and prometheus which I currently having issue running)
• otel-agent-config.yaml
• otel-collector-config.yaml
• .env

to my app.

Also based on these two demos in open-telemetry/opentelemetry-js repo:

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

I came up with my version (sorry for a bit long, really hard to set up a minimum working version due to the lack of docs):

.env

After running docker-compose up -d, I can open Jaeger (http://localhost:16686) and Zipkin UI (http://localhost:9411).

And my ConsoleSpanExporter works in both web client and Express.js server.

However, I tried this OpenTelemetry exporter code in both client and server, I am still having issue to connect OpenTelemetry collector.

Please see my comment about URL inside of the code

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.
    })
  )
);

Any idea? Thanks

The demo you tried is using older configuration and opencensus which should be replaced with otlp receiver. Having said that this is a working example https://github.com/open-telemetry/opentelemetry-js/tree/master/examples/collector-exporter-node/docker So I'm copying the files from there:

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']

This should work fine with opentelemetry-js ver. 0.10.2

Default port for traces is 55680 and for metrics 55681

The link I posted previously - you will always find there the latest up to date working example: https://github.com/open-telemetry/opentelemetry-js/tree/master/examples/collector-exporter-node And for web example you can use the same docker and see all working examples here: https://github.com/open-telemetry/opentelemetry-js/tree/master/examples/tracer-web/

Thank you sooo much for @BObecny's help! This is a complement of @BObecny's answer.

Since I am more interested in integrating with Jaeger. So here is the config to set up with all Jaeger, Zipkin, Prometheus. And now it works on both front end and back end.

First both front end and back end use same exporter code:

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

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

docker-compose.yaml

    ports:
      - "9464:9464"
      - "55680:55680"
      - "55681:55681"
