+Logging Command Errors
+----------------------
+
+Whenever an exception is thrown while running commands, Symfony adds a log
+message for it including the entire failing command. In addition, Symfony
+registers an :doc:`event subscriber </event_dispatcher>` to listen to the
+:ref:`ConsoleEvents::TERMINATE event <console-events-terminate>` and adds a log
+message whenever a command doesn't finish with the ``0`` exit status.
