# Multi-DB Tracing with setup_tracing()

> Trace agents with multiple databases using setup_tracing() in AgentOS.

This example shows how to configure tracing when agents have separate databases using `setup_tracing()`. A dedicated tracing database ensures all traces are stored in one central location.

<Steps>
  <Step title="Create a Python file">
    ```python tracing_multi_db_setup.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
    from agno.tools.hackernews import HackerNewsTools
    from agno.tracing import setup_tracing

    # Set up databases - each agent has its own db
    db1 = SqliteDb(db_file="tmp/db1.db", id="db1")
    db2 = SqliteDb(db_file="tmp/db2.db", id="db2")

    # Dedicated traces database
    db = SqliteDb(db_file="tmp/traces.db", id="traces")

    # Setup tracing with custom configuration
    setup_tracing(
        db=db,
        batch_processing=True,
        max_queue_size=1024,
        max_export_batch_size=256,
    )

    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=db1,
    )

    agent2 = Agent(
        name="Web Search Agent",
        model=OpenAIResponses(id="gpt-5.2"),
        tools=[HackerNewsTools()],
        instructions="You are a web search agent. Answer questions concisely.",
        markdown=True,
        db=db2,
    )

    # Setup AgentOS with dedicated db
    # This ensures traces are written to and read from the same database
    agent_os = AgentOS(
        description="Example app for tracing with multiple databases",
        agents=[agent, agent2],
        db=db,  # Dedicated database for traces
    )
    app = agent_os.get_app()

    if __name__ == "__main__":
        agent_os.serve(app="tracing_multi_db_setup:app", reload=True)
    ```

  <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 tracing_multi_db_setup.py
    ```

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