LLM Tracekit

This library is a modified version of the OpenTelemetry instrumentaion for OpenAI, designed to simplify LLM application development and production tracing and debugging.

Installation

pip install llm-tracekit

Usage

This library serves as a replacement for the OpenTelemetry OpenAI instrumentation - to set up OpenAI instrumentation, follow the manual instrumentation process detailed in the OpenTelemetry OpenAI instrumentation docs and replace opentelemetry.instrumentation.openai_v2 with llm_tracekit.

Activation

from llm_tracekit import OpenAIInstrumentor

OpenAIInstrumentor().instrument()

Full Example

from llm_tracekit import OpenAIInstrumentor, setup_export_to_coralogix
from openai import OpenAI

# Optional: Configure sending spans to Coralogix
# Reads Coralogix connection details from the following environment variables:
# - CX_TOKEN
# - CX_ENDPOINT
# To use, install llm-tracekit[export]
setup_export_to_coralogix(
    service_name="ai-service",
    application_name="ai-application",
    subsystem_name="ai-subsystem",
    capture_content=True,
)

# Activate instrumentation
OpenAIInstrumentor().instrument()

# Example OpenAI Usage
client = OpenAI()
response = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[
        {"role": "user", "content": "Write a short poem on open telemetry."},
    ],
)

Enabling message content

Message content such as the contents of the prompt, completion, function arguments and return values are not captured by default. To capture message content as span attributes, set the environment variable OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT to true.

Most Coralogix AI evaluations will not work without message contents, so it is highly recommended to enable capturing.

Changes from OpenTelemetry

• The user parameter in the OpenAI Chat Completions API is now recorded in the span as the gen_ai.openai.request.user attribute
• The tools parameter in the OpenAI Chat Completions API is now recorded in the span as the gen_ai.openai.request.tools attributes.
• User prompts and model responses are captured as span attributes instead of log events (see Semantic Conventions below)
