Error monitoring and crash aggregation 🔗
Errors are aggregated based on the stack trace. The error stack trace contains the error type and error message in the body of the stack trace. The following table outlines the different ways errors are grouped together depending on the situation.
How errors are grouped together
Errors have a stack trace
Errors are grouped by the hash ID of the stack trace
Errors don’t have a stack trace
Errors are grouped by the hash ID of the message and error type
Errors don’t have an error message
Errors are grouped by the hash ID of the error type
The error ID can represent:
hash ID of a stack trace
hash ID of a message
hash ID of the error type
Mobile crash aggregation 🔗
A crash happens when a user encounters an error and has to exit the app. App errors are all other types of errors that occur but don’t result in the user having to exit the app. For example, ANR (application not responding).
