Defined in:
lib/appsignal/hooks/at_exit.rb

Overview

Stop AppSignal before the app exists.

This is the default behavior and can be customized with the ‘enable_at_exit_hook` option.

When the ‘enable_at_exit_reporter` option is set to `true` (the default), it will report any unhandled errors that will crash the Ruby process.

If this error was previously reported by any of our instrumentation, the error will not also be reported here. This way we don’t report an error from a Rake task or instrumented script twice.
