How to Configure Lightweight Browser Tracing for Debugging at Scale

To configure lightweight browser tracing for debugging at scale, you can fine-tune your sample rate and span collection to make your traces more focused and readable. The `tracesSampleRate` setting allows you to control what percentage of frontend traces are sent to Sentry, while `ignoreResourceSpans` enables you to turn off certain resource spans that contribute to a large trace volume. By adjusting these settings, you can reduce your span volume without lowering your sample rate, which is particularly useful for high-traffic websites or when answering specific questions about user behavior. Additionally, you can customize your auto-instrumentation by ignoring performance API spans or disabling long animation frames, depending on the questions you're trying to answer and the structure of your trace. By asking "what questions are you trying to answer?" and considering both sample rate and configuration settings, you can get the most out of browser tracing for debugging at scale.
