OpenTelemetry Collector Exporter for web and node

This module provides exporter for web and node to be used with opentelemetry-collector - last tested with version 0.12.0.

Installation

npm install --save @opentelemetry/exporter-collector

Traces in Web

The CollectorTraceExporter in Web expects the endpoint to end in /v1/trace.

import { SimpleSpanProcessor } from '@opentelemetry/tracing';
import { WebTracerProvider } from '@opentelemetry/web';
import { CollectorTraceExporter } from '@opentelemetry/exporter-collector';

const collectorOptions = {
  url: '<opentelemetry-collector-url>', // url is optional and can be omitted - default is http://localhost:55681/v1/trace
  headers: {}, //an optional object containing custom headers to be sent with each request
};

const provider = new WebTracerProvider();
const exporter = new CollectorTraceExporter(collectorOptions);
provider.addSpanProcessor(new SimpleSpanProcessor(exporter));

provider.register();

Metrics in Web

The CollectorMetricExporter in Web expects the endpoint to end in /v1/metrics.

import { MetricProvider } from '@opentelemetry/metrics';
import { CollectorMetricExporter } from '@opentelemetry/exporter-collector';
const collectorOptions = {
  url: '<opentelemetry-collector-url>', // url is optional and can be omitted - default is http://localhost:55681/v1/metrics
  headers: {}, //an optional object containing custom headers to be sent with each request
};
const exporter = new CollectorMetricExporter(collectorOptions);

// Register the exporter
const meter = new MeterProvider({
  exporter,
  interval: 60000,
}).getMeter('example-meter');

// Now, start recording data
const counter = meter.createCounter('metric_name');
counter.add(10, { 'key': 'value' });

Traces in Node - JSON over http

const { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');
const { CollectorTraceExporter } =  require('@opentelemetry/exporter-collector');

const collectorOptions = {
  serviceName: 'basic-service',
  url: '<opentelemetry-collector-url>', // url is optional and can be omitted - default is http://localhost:55681/v1/trace
  headers: {
    foo: 'bar'
  }, //an optional object containing custom headers to be sent with each request will only work with http
};

const provider = new BasicTracerProvider();
const exporter = new CollectorTraceExporter(collectorOptions);
provider.addSpanProcessor(new SimpleSpanProcessor(exporter));

provider.register();

Metrics in Node

const { MeterProvider } = require('@opentelemetry/metrics');
const { CollectorMetricExporter } =  require('@opentelemetry/exporter-collector');
const collectorOptions = {
  serviceName: 'basic-service',
  url: '<opentelemetry-collector-url>', // url is optional and can be omitted - default is http://localhost:55681/v1/metrics
};
const exporter = new CollectorMetricExporter(collectorOptions);

// Register the exporter
const meter = new MeterProvider({
  exporter,
  interval: 60000,
}).getMeter('example-meter');

// Now, start recording data
const counter = meter.createCounter('metric_name');
counter.add(10, { 'key': 'value' });
