Send Otel Node traces to Axiom

node.js

const opentelemetry = require('@opentelemetry/sdk-node');
const { getNodeAutoInstrumentations } = require('@opentelemetry/auto-instrumentations-node');
const { OTLPTraceExporter } = require('@opentelemetry/exporter-trace-otlp-proto');
const { BatchSpanProcessor } = require('@opentelemetry/sdk-trace-base');
const { Resource } = require('@opentelemetry/resources');
const { SemanticResourceAttributes } = require('@opentelemetry/semantic-conventions');

// Initialize OTLP trace exporter
const traceExporter = new OTLPTraceExporter({
  url: 'https://api.axiom.co/v1/traces',
  headers: {
    'Authorization': 'Bearer $API_TOKEN',
    'X-Axiom-Dataset': '$DATASET'
  },
});

const resource = new Resource({
  [SemanticResourceAttributes.SERVICE_NAME]: 'node traces', 
});

const sdk = new opentelemetry.NodeSDK({
  spanProcessor: new BatchSpanProcessor(traceExporter),
  resource: resource, // Add the resource here
  instrumentations: [getNodeAutoInstrumentations()],
});

sdk.start();

My lib option is "lib": ["ES2023"],. I'm compiling for Node so I omit the DOM types.

Anyway, I got a hack to make it compile but it still doesn't export the logs. I'm guessing it's something with otel. Maybe you could check with your team for someone that's familiar with logging for OTel in JavaScript.

I could try to configure it with the pino or winston extension directly with Axiom. But I'd prefer auto-instrumentation if it;s possible

The config above is to send traces to Axiom using url: 'https://api.axiom.co/v1/traces You can use our supported SDKs to log into Axiom:

• js sdk: https://github.com/axiomhq/axiom-js
• pino: https://github.com/axiomhq/axiom-js/tree/main/packages/pino
• winston: https://github.com/axiomhq/axiom-js/tree/main/packages/winston

The js logs package for Otel is still under development and experimental: https://opentelemetry.io/docs/instrumentation/js/

Thanks. I got it working it working with the pino package.
