Enriching Events Custom contexts allow you to attach arbitrary data (strings, lists, dictionaries) to an event. Learn how to configure the SDK to capture the user and gain critical pieces of information that construct a unique identity in Sentry. Tags power UI features such as filters and tag-distribution maps. Tags also help you quickly access related events and view the tag distribution for a set of events. Learn more about what Sentry uses to create a trail of events (breadcrumbs) that happened prior to an issue. Learn more about collecting user feedback when an event occurs. Sentry pairs the feedback with the original event, giving you additional insight into issues. Help improve this content Our documentation is open source and available on GitHub. Your contributions are welcome, whether fixing a typo (drat!) to suggesting an update ("yeah, this would be better").
