 In most cases, sending all [transaction](/product/performance/transaction-summary/#what-is-a-transaction) events to Sentry would generate more performance data than you might find useful and might use up your transactions quota too quickly. Sentry provides tools to control the _type_ and _amount_ of transactions that are monitored. This allows you to have transaction data that's actionable and meaningful, and to manage your quota. Applying the proper SDK configuration is an iterative and on-going process, but these tips will show you how to best use Sentry's tools to get the most out of your transaction events.

-All Sentry SDKs support the `beforeSend` callback method. Once implemented, the method is invoked when the SDK captures an event, right before sending it to your Sentry account. It receives the event object as a parameter, so you can use that to modify the event's data or drop it completely (by returning `null`) based on your custom logic and the data available on the event, like _tags_, _environment_, _release version_, and so on. Learn more in [Filtering Events](/platform-redirect/?next=/configuration/filtering/).
+When you configure your the SDK, you can control the number of transactions that are sent to Sentry by setting the [tracing options](/platform-redirect/?next=/configuration/options/%23tracing-options). You can also set up [custom instrumentation](/platform-redirect/?next=/performance/instrumentation/custom-instrumentation/) for performance monitoring to capture certain types of transactions.
