Add Custom Log Settings

Open logging.php file from /config folder.

Inside logging.php search for channels.

Inside channels array, add your settings for custom log.

'channels' => [ ... 'webtutorlog' => [ 'driver' => 'single', 'path' => storage_path('logs/applicationlog.log'), 'level' => 'info', ], ],

webtutorlog is channel name. applicationlog.log is custom log file name where we will store our custom log messages.

storage_path(‘logs/applicationlog.log’) It returns path as / storage/logs/applicationlog.log

Create Test Logs

Open web.php from /routes folder. Add this route into it.

//... Route::get('create-log', function () { \Log::channel('webtutorlog')->info('This is info log level for testing'); \Log::channel('webtutorlog')->warning('This is warning log level for testing'); \Log::channel('webtutorlog')->error('This is error log level for testing'); \Log::channel('webtutorlog')->alert('This is alert log level for testing'); \Log::channel('webtutorlog')->emergency('This is emergency log level for testing'); \Log::channel('webtutorlog')->notice('This is notice log level for testing'); dd('done'); }); //...

Open project to terminal and type the command to start development server

$ php artisan serve


You will get applicationlog.log file inside /storage/logs folder. When you open, you should see these lines added into it.
