Structured logging

To improve Airbrake’s grouping and aggregation of errors, it is strongly advised to use a machine readable format in error messages. Airbrake supports 2 main formats:

  • JSON appearing anywhere in the error message, for example User not found {"id":123,"email":""}.
  • key=value pairs, for example User not found id=123 email="".

In both variants, Airbrake extracts the data from the error message and saves it in the context.messageParams field, which can be used later for aggregation.

Error messages like User 123 with email not found are also parsed, but it is a much less reliable way to send structured data.
