# Basic Workflow Tracing

> Enable tracing and observability for workflows.

Enable tracing for a workflow to automatically capture all workflow operations, step runs, model calls, and tool executions in your database.

<Steps>
  <Step title="Create a Python file">
    ```python basic_workflow_tracing.py theme={null}
