Automatically captured data

Bugsnag automatically captures a variety of data to help you debug your errors. You may wish to avoid capturing some types of data, particularly if there are privacy implications for your users.

Application information

Information about the application can be useful to identify if an error occurs in certain versions.

Data Default value Preventing collection
Bundle version The build-version-number string for the app, set from CFBundleVersion Modify app in a callback
Duration in foreground How long the app has been in the foreground in milliseconds Modify app in a callback
Id The app’s unique package name, set from CFBundleIdentifier Modify app in a callback
In foreground Whether the app was in the foreground at the time of the report Modify app in a callback
Dsym UUIDs An array of UUIDs identifying any dSYM files in the application Modify app in a callback
Duration Milliseconds since the app first launched Modify app in a callback
Version The app’s version, set from CFBundleShortVersionString Modify app in a callback
Type The platform the app runs on Modify app in a callback
Release stage The app’s release stage. This is automatically configured by the notifier to be “production”, unless DEBUG is defined during compilation. Modify app in a callback
Name The name of the executable, set from CFBundleExecutable Modify app in a callback

Device information

Information about the device can be useful to identify if an error is only occurring on some devices.

Data Default value Preventing collection
Id A hash of various device/app specific data Modify device in a callback
Battery level Amount of battery charge available at time of report Modify device in a callback
OS name Name of the operating system Modify device in a callback
Jail broken A boolean value which is true the device is jailbroken Modify device in a callback
Orientation Orientation of the device at time of report Modify device in a callback
Simulator A boolean value which is true if the device is a simulator Modify device in a callback
OS version The user-visible version of the operating system Modify device in a callback
Locale The device’s current locale Modify device in a callback
Free memory Number of bytes of remaining memory that can be allocated Modify device in a callback
Manufacturer The device manufacturer Modify device in a callback
Free disk Number of bytes of remaining disk space Modify device in a callback
Charging A boolean value which is true if the device is charging its battery Modify device in a callback
Model number The model of the device Modify device in a callback
Word size Word size of OS (32-bit or 64-bit) Modify device in a callback
Model The model of the device Modify device in a callback
Timezone The device’s timezone Modify device in a callback
Total memory Total amount of memory available on the device Modify device in a callback

User information

User information is used to show you which errors are impacting the most users. Set your own user identifiers if you want to be able to find errors affecting individual users.

Data Default value Preventing collection
Id The user ID is set as the same value as device.id. Set the user to nil and remove device.id in a callback.

Error information

Modifying error information may affect error grouping.

Data Default value Preventing collection
Context The screen name of the current foreground ViewController Modify context in a callback
Error class The class of the error that occurred Modify errorClass in a callback
Error message The message of the error that occurred Modify errorMessage in a callback
Stack trace A stacktrace of the filename, method, and line number of where the error occurred in the source code, if this information is available Call report.attachCustomStacktrace() in a callback
Threads Traces of thread stack frames at the time of reporting an error, including the filename, method, and line numbers of source code. Set Bugsnag.setThreadTracingEnabled to false at initialisation

Breadcrumbs are automatically recorded for common actions and can be helpful to reproduce errors.

UITextViewTextDidBeginEditingNotification Notification when the user begins editing a text view Disable automatic breadcrumb collection
UITextFieldTextDidEndEditingNotification Notification when the user ends editing a text field Disable automatic breadcrumb collection
