Simple LLM Integration

Essential pattern for tracing basic LLM calls with Noveum

This example shows how to trace a basic LLM call using Noveum. You'll learn how to set up tracing, add context, and view results in the dashboard.

🎯 Use Case

Customer Support Chatbot: A simple chatbot that answers customer questions using GPT-4. We'll trace the LLM call to monitor performance, costs, and response quality.

🚀 Essential Integration Pattern

1. Initialize Noveum

Add this once at the start of your application:

import noveum_trace
 
noveum_trace.init(
    api_key=os.getenv("NOVEUM_API_KEY"),
    project="customer-support-bot",
    environment="development"
)

2. Trace Your LLM Call

Wrap your LLM call with the tracing context managers:

from noveum_trace import trace_llm, trace_operation
import openai
 
# Trace the entire operation
with trace_operation("customer-support-query") as main_span:
    # Add context to the main span
    main_span.set_attributes({
        "customer.id": customer_id,
        "query.type": "customer_support"
    })
    
    # Trace the specific LLM call
    with trace_llm(model="gpt-4", provider="openai") as llm_span:
        # Make your LLM call
        response = openai.chat.completions.create(
            model="gpt-4",
            messages=[
                {"role": "system", "content": "You are a helpful assistant."},
                {"role": "user", "content": user_question}
            ]
        )
        
        # Track token usage for cost monitoring
        llm_span.set_usage_attributes(
            input_tokens=response.usage.prompt_tokens,
            output_tokens=response.usage.completion_tokens
        )
    
    return response.choices[0].message.content

📊 Key Concepts

Trace Structure

trace_operation() creates a parent span for the entire operation
trace_llm() creates a child span specifically for the LLM call
Spans are nested to show the relationship between operations

Adding Context

Use set_attributes() to add metadata that helps you filter and analyze traces:

span.set_attributes({
    "customer.id": customer_id,
    "query.type": "support",
    "environment": "production"
})

Tracking Token Usage

Always track token usage for cost monitoring and optimization:

llm_span.set_usage_attributes(
    input_tokens=response.usage.prompt_tokens,
    output_tokens=response.usage.completion_tokens
)

📈 What You'll See in the Dashboard

Your traces will appear in the Noveum dashboard with:

Nested span structure showing the operation hierarchy
Duration for each operation
Token usage and estimated costs
Custom attributes you've added
Timeline of events

🔧 Optional: Adding More Context

You can add custom attributes to track business-specific metrics:

# Add custom business context
main_span.set_attributes({
    "customer.tier": "premium",
    "customer.region": "us-west",
    "query.category": "billing"
})
 
# Track quality metrics
llm_span.set_attributes({
    "response.quality_score": 0.95,
    "response.helpfulness": "high"
})

🔍 Quick Troubleshooting

If traces aren't appearing in the dashboard:

Verify your NOVEUM_API_KEY is set correctly
Wait 30-60 seconds for traces to process
Check that you're viewing the correct project
