Traceloop’s OpenLLMetry is an open source project that allows you to easily start monitoring and debugging the execution of your LLM app.

Traceloop’s non-intrusive instrumentation combined with Portkey’s intelligent gateway provides comprehensive observability without modifying your application code, while adding routing intelligence, caching, and failover capabilities.

​
Why Traceloop + Portkey?

Non-Intrusive Monitoring

Automatic instrumentation without changing your application code

OpenTelemetry Native

Built on industry-standard OpenTelemetry for maximum compatibility

Flexible Export Options

Send traces to Portkey or any OpenTelemetry-compatible backend

Enhanced Intelligence

Portkey adds gateway features like caching, fallbacks, and load balancing

​
Quick Start

​
Prerequisites

  • Python
  • Portkey account with API key
  • OpenAI API key (or use Portkey’s virtual keys)

​
Step 1: Install Dependencies

Install the required packages for Traceloop and Portkey integration:

pip install openai traceloop-sdk portkey-ai

​
Step 2: Initialize Traceloop

Configure Traceloop to send traces to Portkey’s OpenTelemetry endpoint:

from traceloop.sdk import Traceloop

# Initialize Traceloop with Portkey's endpoint
Traceloop.init(
    disable_batch=True,  # Process traces immediately
    api_endpoint="https://api.portkey.ai/v1/logs/otel",
    headers="x-portkey-api-key=YOUR_PORTKEY_API_KEY",
    telemetry_enabled=False  # Disable Traceloop's own telemetry
)

​
Step 3: Configure Portkey Gateway

Set up the OpenAI client to use Portkey’s intelligent gateway:

from openai import OpenAI
from portkey_ai import createHeaders

# Use Portkey's gateway for intelligent routing
client = OpenAI(
    api_key="YOUR_OPENAI_API_KEY",  # Or use a dummy value with virtual keys
    base_url="https://api.portkey.ai/v1",
    default_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        virtual_key="YOUR_VIRTUAL_KEY"  # Optional: Use Portkey's secure key management
    )
)

​
Step 4: Make Instrumented LLM Calls

Your LLM calls are now automatically traced by Traceloop and enhanced by Portkey:

# Make calls through Portkey's gateway
# Traceloop automatically instruments the call
response = client.chat.completions.create(
    model="gpt-4",
    messages=[
        {
            "role": "user",
            "content": "Explain the benefits of OpenTelemetry for LLM applications"
        }
    ],
    temperature=0.7
)

print(response.choices[0].message.content)

# You now get:
# 1. Automatic, non-intrusive tracing from Traceloop
# 2. Gateway features from Portkey (caching, fallbacks, routing)
# 3. Combined insights in Portkey's dashboard

​
Complete Example

Here’s a full example bringing everything together:

from traceloop.sdk import Traceloop
from openai import OpenAI
from portkey_ai import createHeaders

# Step 1: Initialize Traceloop with Portkey endpoint
Traceloop.init(
    disable_batch=True,
    api_endpoint="https://api.portkey.ai/v1/logs/otel",
    headers="x-portkey-api-key=YOUR_PORTKEY_API_KEY",
    telemetry_enabled=False
)

# Step 2: Configure Portkey Gateway
client = OpenAI(
    api_key="YOUR_OPENAI_API_KEY",
    base_url="https://api.portkey.ai/v1",
    default_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        virtual_key="YOUR_VIRTUAL_KEY"
    )
)

# Step 3: Make instrumented calls
response = client.chat.completions.create(
    model="gpt-4",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "What makes observability important for production AI?"}
    ]
)

print(response.choices[0].message.content)
