OpenTelemetry Collector Exporter for node with protobuf

This module provides exporter for node to be used with opentelemetry-collector - last tested with version 0.6.0.

Installation

npm install --save @opentelemetry/exporter-collector-proto

Traces in Node - PROTO over http

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

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 - PROTO over http

const { MeterProvider } = require('@opentelemetry/metrics');
const { CollectorMetricExporter } =  require('@opentelemetry/exporter-collector-proto');
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' });
