If the application is in the +background for less than 30 seconds, we do not start the session again. +Applications that are active even on the background (for example, a music +player) should track the sessions manually for the background process. ### Server-Mode/Request-Mode Sessions - +These are typically high in volume since each session corresponds to a single +request. Sessions, whether application-mode or request-mode, are submitted to Sentry so you can track the usage and adoption of your application. When a user of your application experiences a crash, error, or abnormal exit, the session will be flagged accordingly, and Sentry calculates derived metrics. The metrics include data such as the number of users that didn't experience a crash in the specified time range.
