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
Runtime versions	The version of clang used to compile the app	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

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

Data	Default value	Preventing collection
NSControlTextDidBeginEditingNotification	Notification when the user begins editing a text field, including the accessibilityLabel of the control	Disable automatic breadcrumb collection
NSControlTextDidEndEditingNotification	Notification when the user ends editing a text field, including the accessibilityLabel of the control	Disable automatic breadcrumb collection
NSTableViewSelectionDidChangeNotification	Notification when the user selects a different row in a table view	Disable automatic breadcrumb collection
NSMenuWillSendActionNotification	Notification when a menu item action will be dispatched	Disable automatic breadcrumb collection
NSApplicationDidBecomeActiveNotification	Notification when the application becomes active	Disable automatic breadcrumb collection
NSApplicationDidResignActiveNotification	Notification when the application becomes inactive	Disable automatic breadcrumb collection
NSApplicationDidHideNotification	Notification when the application becomes hidden	Disable automatic breadcrumb collection
NSApplicationDidUnhideNotification	Notification when the application becomes unhidden	Disable automatic breadcrumb collection
NSApplicationWillTerminateNotification	Notification when the application will terminate	Disable automatic breadcrumb collection
NSWorkspaceScreensDidSleepNotification	Notification when the device screen goes to sleep	Disable automatic breadcrumb collection
NSWorkspaceScreensDidWakeNotification	Notification when the device screen wakes from sleep	Disable automatic breadcrumb collection
NSWindowWillCloseNotification	Notification when the window is about to close	Disable automatic breadcrumb collection
NSWindowDidBecomeKeyNotification	Notification when the window becomes the key window	Disable automatic breadcrumb collection
NSWindowWillMiniaturizeNotification	Notification when the window will miniaturize	Disable automatic breadcrumb collection
NSWindowDidEnterFullScreenNotification	Notification when the window will enter full screen	Disable automatic breadcrumb collection
NSWindowDidExitFullScreenNotification	Notification when the window will exit full screen	Disable automatic breadcrumb collection
