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

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

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.
