Configurations

OTEL Collector

Refer to the OTEL configuration page for details on running and configuring the OpenTelemetry Collector with a custom configuration file.

Ensure that you configure the Langtrace API token in the OTEL collector configuration file before proceeding.

Python SDK

To send traces to the OTEL Collector, install the required OpenTelemetry exporter package:

pip install opentelemetry-exporter-otlp-proto-http

Implementation

Initialize the Langtrace SDK with a custom remote exporter using the OTLPSpanExporter to send traces.

Example pre-requisite steps for running the code.

Create a folder and set up a virtual environment for Python:

mkdir langtrace-otel
cd langtrace-otel
touch langtrace_otel.py
python3 -m venv venv
source venv/bin/activate

Install the OpenAI and Langtrace Python SDK:

pip install openai langtrace-python-sdk

Export the OpenAI API key:

export OPENAI_API_KEY="your-openai-api-key"

langtrace_otel.py

from langtrace_python_sdk import langtrace
from openai import OpenAI
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter


# Configure the OTLP exporter to use the correct endpoint
otlp_endpoint = "http://localhost:4318/v1/traces"
otlp_exporter = OTLPSpanExporter(
    endpoint=otlp_endpoint,
    headers={"Content-Type": "application/json"}
)
langtrace.init(custom_remote_exporter=otlp_exporter, batch=False)


def chat_with_openai():
    client = OpenAI()
    messages = [
      {
          "role": "system",
          "content": "How many states of matter are there?",
      },
    ]
    chat_completion = client.chat.completions.create(
        messages=messages,
        stream=False,
        model="gpt-3.5-turbo",
    )
    print(chat_completion.choices[0].message.content)
