Ignore errors

Sometimes an error is raised which AppSignal shouldn't send alert about. It's not desired to capture an exception with a begin..rescue block just to prevent AppSignal from alerting you. Instead, the exception should be handled by the framework the application is using.

To prevent AppSignal from picking up these errors and alerting you, you can add exceptions that you want to ignore to the list of ignored errors in your configuration.

# config/appsignal.yml
default: &defaults
  ignore_errors:
    - ActiveRecord::RecordNotFound
    - ActionController::RoutingError

You can also configure ignore exceptions via an environment variable.

export APPSIGNAL_IGNORE_ERRORS="ActiveRecord::RecordNotFound,ActionController::RoutingError"

Any exceptions defined here will not be sent to AppSignal and will not trigger a notification.
