Full stack visibility into app health and user experience

A span is a measurement of the time taken to perform a particular operation. It has a start and end time. Every operation that BugSnag Real User Monitoring measures results in a span being sent to BugSnag servers. This includes high level user operations, such as an app start or a web page load, as well as the more detailed sub-operations such as making a network request or loading a fragment of a view.

We recommend you evaluate your trial experience within BugSnag and closely monitor how many spans were sent during your trial and the percentage of your production environment that equated to. We then suggest you determine if you received an adequate level of insight into app performance for your users. Other factors that may influence your decision are how many apps you are deploying and if you are looking to monitor select areas of your application vs your entire application.

BugSnag Real User Monitoring uses dynamic sampling to ensure your users’ apps send only enough spans to meet your span quota. We take your monthly span limit and automatically set a daily sample rate that distributes the quota across the entire month, so you maintain a consistent daily volume. Our predictable pricing is designed for you to only pay for what you need and make sure you get everything you pay for – eliminating surprise costs because of unpredictable spikes and ensuring you always have performance insights.

An event is either an unhandled exception (often called an error or crash) that has been detected by BugSnag or any handled exceptions that you choose to report.

Minidump events (native crashes reported by Electron apps, or apps integrating Breakpad or Crashpad) each count as 5 events for billing purposes. This is due to the additional costs associated with receiving and processing minidump events.

• An unhandled exception usually means the application crashed or an operation failed unexpectedly. BugSnag automatically captures all unhandled exceptions and corresponding diagnostic information.
• A handled exception is an anticipated error. It can be reported to BugSnag with any relevant diagnostic information.

A seat is shorthand for a collaborator — anyone who logs in to BugSnag.
