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
Type	The primary app framework	Override the app_type property during BugSnag configuration

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 hostname of the server	Override the hostname property during BugSnag configuration
Runtime versions	The version of Ruby and supported frameworks in use	Modify metadata.device in a callback

Rake task information

BugSnag automatically captures data about the running task, on a rake_task metadata tab.

This tab can be removed in its entirety using the clear_metadata method within a middleware or callback.

Data	Default value	Preventing collection
Name	The task’s name	Filter name using redacted_keys
Description	The task’s description	Filter description using redacted_keys
Arguments	Arguments provided to the task	Filter arguments using redacted_keys

Error information

Modifying error information may affect error grouping.

Data	Default value	Preventing collection
Error class	The exception’s class name	Override the error data within an event using a callback and the exceptions method
Error message	The exception’s message	Override the error data within an event using a callback and the exceptions method
Stack trace	A stack trace derived from the exception, containing code, filenames, methods and line numbers	Override the error data within an event using a callback and the exceptions method
Context	The name of the task	Override the event’s context using a callback or custom middleware

Mongo breadcrumbs

Breadcrumbs contain information that can help you track down the root cause of errors.

BugSnag will automatically add a subscriber if the Mongo ruby driver gem is detected, allowing breadcrumbs to be captured with each transaction.

All breadcrumbs can be filtered as described in the discarding and amending breadcrumbs section.

A full list of the Mongo breadcrumbs and data captured can be found in the table below.

event id	breadcrumb message	type	captured metaData
succeeded	Mongo query succeeded	PROCESS	command_name, database_name, operation_id, request_id, duration, collection, filters
failed	Mongo query failed	PROCESS	command_name, database_name, operation_id, request_id, duration, message, collection, filters

Filter Data

The filters metadata captured in a breadcrumb will only ever contain keys used in a query, never values.
