# Set Up Tracing | Sentry for Python

## [Prerequisites](https://docs.sentry.io/platforms/python/tracing.md#prerequisites)

* You have the [Python SDK installed](https://docs.sentry.io/platforms/python.md) (version 0.11.2 or higher)

## [Configure](https://docs.sentry.io/platforms/python/tracing.md#configure)

To enable tracing in your application, adjust the `traces_sample_rate` based on the number of trace samples you want to send to Sentry by adding the highlighted code snippet below. (Setting a value of `1.0` will send 100% of your traces.)

```python
import sentry_sdk

sentry_sdk.init(
    dsn="___PUBLIC_DSN___",
    # Add data like request headers and IP for users, if applicable;
    # see https://docs.sentry.io/platforms/python/data-management/data-collected/ for more info
    send_default_pii=True,
    # Set traces_sample_rate to 1.0 to capture 100%
    # of transactions for tracing.
+   traces_sample_rate=1.0,
)
```

If you’re adopting Tracing in a high-throughput environment, we recommend testing prior to deployment to ensure that your service’s performance characteristics maintain expectations.
