Set Up Tracing

With Tracing, Sentry tracks your software performance, measuring metrics like throughput and latency, and displays the impact of errors across multiple systems.

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.)

Copied
import sentry_sdk

sentry_sdk.init(
    dsn="https://examplePublicKey@o0.ingest.sentry.io/0",
+   # We recommend adjusting this value in production
+   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.
