# Splunk Distribution of OpenTelemetry for Node.js

The Splunk Distribution of [OpenTelemetry JS](https://github.com/open-telemetry/opentelemetry-js) integrates with Splunk APM and automatically instruments your Node application to capture traces, collect runtime metrics, and CPU and memory profiles.

This distribution comes with the following defaults:

- [W3C tracecontext and baggage propagation](https://www.w3.org/TR/trace-context)
- [OTLP exporter](https://www.npmjs.com/package/@opentelemetry/exporter-trace-otlp-proto) configured to send spans to a locally running OpenTelemetry Collector over HTTP.
- Many bundled [instrumentations](#default-instrumentation-packages)

If you're using the SignalFx Tracing Library for Node and want to migrate to the Splunk Distribution of OpenTelemetry Node, see [Migrate from the SignalFx Tracing Library for NodeJS](https://quickdraw.splunk.com/redirect/?product=Observability&version=current&location=nodejs.application.migrate) in the official documentation.

## Get started

For complete instructions on how to get started with the Splunk Distribution of OpenTelemetry JS, see [Instrument a Node application for Splunk Observability Cloud](https://quickdraw.splunk.com/redirect/?product=Observability&version=current&location=nodejs.application.gdi) in the official documentation.

## Correlate traces and logs

The Splunk Distribution of OpenTelemetry JS automatically injects trace metadata into logs so that Node.js logging libraries can access it. You can use trace metadata to correlate traces with log events and explore logs in Observability Cloud.

For more information, see [Connect Node.js trace data with logs for Splunk Observability Cloud](https://quickdraw.splunk.com/redirect/?product=Observability&version=current&location=nodejs.application.tracelogs) in the official documentation.
