When is data removed from Airbrake
In order to reduce space consumed by old or redundant data Airbrake may remove backtraces and extra request information from individual error occurances. If data is removed, the Rails environment name, error class, error message, file, controller, action, and date are preserved. When information has been removed, you will see information message that reads:
“Some information on the occurance of this error has been removed from the database.”
Airbrake deletes this information based on your plan’s retention period.
