Traces in Node - PROTO over http

const { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');
const { OTLPTraceExporter } =  require('@opentelemetry/exporter-otlp-proto');

const collectorOptions = {
  url: '<opentelemetry-collector-url>', // url is optional and can be omitted - default is http://localhost:55681/v1/traces
  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 OTLPTraceExporter(collectorOptions);
provider.addSpanProcessor(new SimpleSpanProcessor(exporter));

provider.register();

Metrics in Node - PROTO over http

const { MeterProvider } = require('@opentelemetry/sdk-metrics-base');
const { OTLPMetricExporter } =  require('@opentelemetry/exporter-otlp-proto');
const collectorOptions = {
  url: '<opentelemetry-collector-url>', // url is optional and can be omitted - default is http://localhost:55681/v1/metrics
};
const exporter = new OTLPMetricExporter(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' });
