Laravel 4 added an Artisan command to tail the laravel.log file on a remote connection. This feature was removed from Laravel 5 and I have to assume this is because of a change to using daily log files.
If this is something you relied upon, Freek Van der Herten, has created a package to add this back in. Currently it only supports tailing the local log files, but remote will be added soon.
Laravel 5 Artisan Tail Command is a post from Laravel News.
