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.

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
Hostname	The result of os.hostname() on the device (or process.env.DYNO when running on Heroku)	Modify device in a callback
Runtime versions	The value of process.versions which lists the version of Node.js and its dependencies	Modify device in a callback

Request information

Details about the request can be helpful to reproduce errors.

Data	Default value	Preventing collection
URL	The full URL requested by the client	Modify request in a callback
Path	The URL path of the request	Modify request in a callback
HTTP method	The request method, e.g. GET, POST	Modify request in a callback

Inline script content	The contents of an inline script where an error occurred	Modify errors[].stacktrace in a callback
Stack trace	The URL of the file where the error occurred, method and line number	Modify errors[].stacktrace in a callback
