Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

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.

//...

use Illuminate\Support\Facades\Log;

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');
     
});

//...

Application Testing

Run this command into project terminal to start development server,

php artisan serve

URL – http://127.0.0.1:8000/create-log

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