Unity Attributes

This page defines the attributes that are available to customize error and crash reports for Unity.

Attributes list

Attributes are additional metadata that can be attached to error and crash reports. You can use attributes to filter, aggregate, analyze, and debug errors in the Backtrace console.

All attributes listed below are captured by the Backtrace Unity SDK, although not all attributes are indexed by default. Non-indexed attributes cannot be used in queries. For more information about indexing, see Indexing Attributes.


You can also define custom attributes. For more information, see Configuration.
