fiddler-strands 0.1.0

Fiddler SDK for Strands Agent instrumentation with OpenTelemetry

Fiddler Strands SDK

OpenTelemetry instrumentation SDK for Strands AI agents, providing automatic observability and monitoring capabilities through Fiddler's platform.

Features

• 🎯 Automatic Instrumentation: Zero-code instrumentation of Strands agents using OpenTelemetry
• 🔍 Built-in Observability: Automatic logging hooks for agent interactions
• 📊 Fiddler Integration: Custom span processors for enhanced trace analysis
• 🛠️ Extensible: Easy to add custom hooks and processors
• 🚀 Production Ready: Built on OpenTelemetry standards

Installation

Using uv (Recommended)

# Install the SDK
uv add fiddler-strands

# For development
uv add fiddler-strands[dev]

# For running examples
uv add fiddler-strands[examples]

Using pip

pip install fiddler-strands

Quick Start

Basic Usage

import os
from strands import Agent
from strands.models.openai import OpenAIModel
from strands.telemetry import StrandsTelemetry
from fiddler_strandsagents import StrandsAgentInstrumentor

strands_telemetry = StrandsTelemetry()
strands_telemetry.setup_otlp_exporter()
strands_telemetry.setup_console_exporter()
# Enable automatic instrumentation
StrandsAgentInstrumentor(strands_telemetry).instrument()

# Create your agent as usual - LoggingHook will be automatically injected
model = OpenAIModel(api_key=os.getenv("OPENAI_API_KEY"))
agent = Agent(model=model, system_prompt="You are a helpful assistant")

# Use your agent - all interactions will be automatically instrumented
response = agent("Hello, how are you?")

Examples

The examples/ directory contains complete working examples:

• travel_agent.py: Complete travel booking agent with tools
• async_travel_agent.py: Async version of the travel booking agent

API Reference

StrandsAgentInstrumentor

The main instrumentor class for automatic agent instrumentation.

from fiddler_strandsagents import StrandsAgentInstrumentor

instrumentor = StrandsAgentInstrumentor()

# Enable instrumentation
instrumentor.instrument()

# Check if instrumentation is active
is_active = instrumentor.is_instrumented_by_opentelemetry

# Disable instrumentation
instrumentor.uninstrument()

Development

Setup Development Environment

# Clone the repository
