Arize Phoenix via OpenInference (Local Collector)

Overview

This example demonstrates how to instrument your Agno agent with OpenInference and send traces to a local Arize Phoenix collector.

Code

import os

from agno.agent import Agent
from agno.models.openai import OpenAIChat
from agno.tools.duckduckgo import DuckDuckGoTools
from phoenix.otel import register

# Set the local collector endpoint for Arize Phoenix
os.environ["PHOENIX_COLLECTOR_ENDPOINT"] = "http://localhost:6006"

# Configure the Phoenix tracer
tracer_provider = register(
    project_name="agno-stock-price-agent",  # Default is 'default'
    auto_instrument=True,  # Automatically use the installed OpenInference instrumentation
)

# Create and configure the agent
agent = Agent(
    name="Stock Price Agent",
    model=OpenAIChat(id="gpt-5-mini"),
    tools=[DuckDuckGoTools()],
    instructions="You are an internet search agent. Find and provide accurate information on any topic.",
    debug_mode=True,
)

# Use the agent
agent.print_response("What are the latest developments in artificial intelligence?")
