# Basic Agent Tracing

> Trace agents with Agno in AgentOS.

This example shows how to enable tracing for an agent in AgentOS. Simply set `tracing=True` and all agent runs, model calls, and tool executions are automatically captured.

<Steps>
  <Step title="Create a Python file">
    ```python basic_agent_tracing.py theme={null}
    from agno.agent import Agent
    from agno.db.sqlite import SqliteDb
    from agno.models.openai import OpenAIResponses
    from agno.os import AgentOS
    from agno.tools.hackernews import HackerNewsTools

    # Set up database
    db = SqliteDb(db_file="tmp/traces.db")

    agent = Agent(
        name="HackerNews Agent",
        model=OpenAIResponses(id="gpt-5.2"),
        tools=[HackerNewsTools()],
        instructions="You are a hacker news agent. Answer questions concisely.",
        markdown=True,
        db=db,
    )

    # Setup AgentOS with tracing enabled
    agent_os = AgentOS(
        description="Example app for tracing HackerNews",
        agents=[agent],
        tracing=True,  # Enable tracing for all agents
    )
    app = agent_os.get_app()

    if __name__ == "__main__":
        agent_os.serve(app="basic_agent_tracing:app", reload=True)
    ```
  </Step>

  <Step title="Install dependencies">
    ```bash theme={null}
    uv pip install -U openai agno opentelemetry-api opentelemetry-sdk openinference-instrumentation-agno
    ```
  </Step>

  <Step title="Export your OpenAI API key">
    <CodeGroup>
      ```bash Mac/Linux theme={null}
      export OPENAI_API_KEY="your_openai_api_key_here"
      ```

      ```bash Windows theme={null}
      $Env:OPENAI_API_KEY="your_openai_api_key_here"
      ```
    </CodeGroup>
  </Step>

  <Step title="Run AgentOS">
    ```bash theme={null}
    python basic_agent_tracing.py
    ```

    Your AgentOS will be available at `http://localhost:7777`. View traces in the AgentOS dashboard.
