In order to visualize and analyze your traces and metrics, you will need to export them to a backend such as Jaeger or Zipkin. OpenTelemetry JS provides exporters for some common open source backends.

Below you will find some introductions on how to setup backends and the matching exporters.

Jaeger

To set up Jaeger as quickly as possible, run it in a docker container:

$ docker run -d --name jaeger \
  -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
  -p 5775:5775/udp \
  -p 6831:6831/udp \
  -p 6832:6832/udp \
  -p 5778:5778 \
  -p 16686:16686 \
  -p 14268:14268 \
  -p 14250:14250 \
  -p 9411:9411 \
  jaegertracing/all-in-one:latest

Install the exporter package as a dependency for your application:

npm install --save @opentelemetry/exporter-jaeger

Update your opentelemetry configuration to use the exporter and to send data to your jaeger backend:

const { JaegerExporter } = require("@opentelemetry/exporter-jaeger");
const { BatchSpanProcessor } = require("@opentelemetry/tracing");

provider.addSpanProcessor(new BatchSpanProcessor(new JaegerExporter()))

Zipkin

To set up Zipkin as quickly as possible, run it in a docker container:

docker run --rm -d -p 9411:9411 --name zipkin openzipkin/zipkin

Install the exporter package as a dependency for your application:

npm install --save @opentelemetry/exporter-zipkin

Update your opentelemetry configuration to use the exporter and to send data to your zipkin backend:

const { ZipkinExporter } = require("@opentelemetry/exporter-zipkin");
const { BatchSpanProcessor } = require("@opentelemetry/tracing");

provider.addSpanProcessor(new BatchSpanProcessor(new ZipkinExporter()))

Prometheus

To set up Prometheus as quickly as possible, run it in a docker container. You will need a prometheus.yml to configure the backend, use the following example and modify it to your needs:

global:
  scrape_interval: 15s
  evaluation_interval: 15s

scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]

With this file you can now start the docker container:

docker run \
    -p 9090:9090 \
    -v ${PWD}/prometheus.yml:/etc/prometheus/prometheus.yml \
    prom/prometheus

Update your opentelemetry configuration to use the exporter and to send data to your prometheus backend:

const { PrometheusExporter } = require('@opentelemetry/exporter-prometheus');
const { MeterProvider }  = require('@opentelemetry/metrics');
const meter = new MeterProvider({
  exporter: new PrometheusExporter({port: 9090}),
  interval: 1000,
}).getMeter('prometheus');

OpenTelemetry Collector

If you are looking for a vendor-agnostic way to receive, process and export your telemetry data follow the instructions to setup a OpenTelemetry collector
