Traceloop is a platform for observability and evaluation of LLM outputs. It allows you to deploy changes to prompts and model configurations with confidence, without breaking existing functionality.

​
Connecting OpenLLMetry to Traceloop directly

You need an API key to send traces to Traceloop. API keys are scoped to a specific project and environment.To generate an API key:
  1. Go to Settings → Organization
  2. Click on your project (or create a new one)
  3. Select an environment (Development, Staging, Production, or custom)
  4. Click Generate API key
  5. Copy the key immediately - it won’t be shown again after you close or reload the page

Set the API key as an environment variable named TRACELOOP_API_KEY: 
export TRACELOOP_API_KEY=your_api_key_here
Done! You’ll get instant visibility into everything that’s happening with your LLM. If you’re calling a vector DB, or any other external service or database, you’ll also see it in the Traceloop dashboard.

Using an OpenTelemetry Collector

If you are using an OpenTelemetry Collector, you can route metrics and traces to Traceloop by simply adding an OTLP exporter to your collector configuration. 
receivers:
  otlp:
    protocols:
      http:
        endpoint: 0.0.0.0:4318
processors:

  otlphttp/traceloop:
    endpoint: "https://api.traceloop.com" # US instance
    headers:
      "Authorization": "Bearer <YOUR_API_KEY>"

  pipelines:
    traces:
      receivers: [otlp]
      processors: [batch]
      exporters: [otlphttp/traceloop]
You can route OpenLLMetry to your collector by following the OpenTelemetry Collector integration instructions.
