OpenInference OpenLLMetry (Traceloop)

Python auto-instrumentation library for OpenLLMetry. This library allows you to convert OpenLLMetry traces to OpenInference, which is OpenTelemetry compatible, and view those traces in Arize Phoenix or Arize AX.

Installation

pip install openinference-instrumentation-openllmetry

Quickstart

This quickstart shows you how to view your OpenLLMetry traces in Phoenix.

Install required packages.

pip install arize-phoenix opentelemetry-sdk opentelemetry-exporter-otlp opentelemetry-instrumentation-openai

Start Phoenix in the background as a collector. By default, it listens on http://localhost:6006. You can visit the app via a browser at the same address. (Phoenix does not send data over the internet. It only operates locally on your machine.)

phoenix serve

Here's a simple example that demonstrates how to view convert OpenLLMetry traces into OpenInference and view those traces in Phoenix:

import os
import grpc
import openai
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter
from phoenix.otel import register
from openinference.instrumentation.openllmetry import OpenInferenceSpanProcessor
from opentelemetry.instrumentation.openai import OpenAIInstrumentor

# Set your OpenAI API key
os.environ["OPENAI_API_KEY"] = "YOUR_OPENAI_API_KEY"

# Set up the tracer provider
tracer_provider = register(
    project_name="default" #Phoenix project name
)

tracer_provider.add_span_processor(OpenInferenceSpanProcessor())
    
tracer_provider.add_span_processor(
    BatchSpanProcessor(
        OTLPSpanExporter(
            endpoint="http://localhost:4317", #if using phoenix cloud, change to phoenix cloud endpoint (phoenix cloud space -> settings -> endpoint/hostname)
            headers={},
            compression=grpc.Compression.Gzip,  # use enum instead of string
        )
    )
)


OpenAIInstrumentor().instrument(tracer_provider=tracer_provider)

# Define and invoke your OpenAI model
client = openai.OpenAI()

messages = [
        {"role": "user", "content": "What is the national food of Yemen?"}
    ]

response = client.chat.completions.create(
    model="gpt-4",
    messages=messages,
)

# Now view your converted OpenLLMetry traces in Phoenix!

This example:

Uses OpenLLMetry Instrumentor to instrument the application.
Defines a simple OpenAI model and runs a query
Queries are exported to Phoenix using a span processor.

The traces will be visible in the Phoenix UI at http://localhost:6006.
