Laravel 9 Log

Laravel 9 log is an integral part of the Laravel 9 application. Basically, it is used as an application for monitoring the application activity. Laravel 9 has robust log services for converting log messages into a file. Today, we will demonstrate Laravel 9 logging. This tutorial helps you to understand your application status. What’s going on with your application. If there were an error in your software, you would see the system error message in your log file. Laravel 9 has a default logging that is based on the Laravel channel.

How It Works

Laravel 9 allows developers to log messages about the system behavior of any application to files, such as the system of error logs, and send them to notify the development teams.

It is based on the Laravel 9 channels. Channels are a specific way of writing a system’s log message. Every channel represents a different destination, and we can send messages to different channels simultaneously.

  1. Process One: Install Laravel 9 in the System
  2. Process Two: Configure Log in Project
  3. Process Three: Run and Test the System

Process One: Install Laravel 9 in the System

We have to run the following command to install our log project:

composer create-project laravel/laravellogProject

It should look like the following image:

Then go to the project root directory and open the logging project.

Process Two: Configure Log in Project

All the project configuration options are located in your application config folder. Now, go to the logging.php file located in the config folder. The logging.php file allows developers to configure logging channels by adding, updating, or deleting.

By default, it should look like the following image:

The stack channel is selected by default. The channels look like the following image in the logging file:

    'channels' => [
        'stack' => [
          => 'stack',
            'channels' => ['single'],
            'ignore_exceptions' => false,

        'single' => [
            'driver' => 'single',
            'path' =>storage_path('logs/laravel.log'),
            'level' =>env('LOG_LEVEL', 'debug'),

        'daily' => [
            'driver' => 'daily',
            'path' =>storage_path('logs/laravel.log'),
            'level' =>env('LOG_LEVEL', 'debug'),
            'days' => 14,

        'slack' => [
            'driver' => 'slack',
            'url' => env('LOG_SLACK_WEBHOOK_URL'),
            'username' => 'Laravel Log',
            'emoji' =>':boom:',
            'level' =>env('LOG_LEVEL', 'critical'),

        'papertrail' => [
            'driver' => 'monolog',
            'level' =>env('LOG_LEVEL', 'debug'),
            'handler' =>env('LOG_PAPERTRAIL_HANDLER', SyslogUdpHandler::class),
            'handler_with' => [
                'host' => env('PAPERTRAIL_URL'),
                'port' => env('PAPERTRAIL_PORT'),
                'connectionString' => 'tls://'.env('PAPERTRAIL_URL').':'.env('PAPERTRAIL_PORT'),

        'stderr' => [
            'driver' => 'monolog',
            'level' =>env('LOG_LEVEL', 'debug'),
            'handler' =>StreamHandler::class,
            'formatter' => env('LOG_STDERR_FORMATTER'),
            'with' => [
                'stream' => 'php://stderr',

        'syslog' => [
            'driver' => 'syslog',
            'level' =>env('LOG_LEVEL', 'debug'),

        'errorlog' => [
            'driver' => 'errorlog',
            'level' =>env('LOG_LEVEL', 'debug'),

        'null' => [
            'driver' => 'monolog',
            'handler' =>NullHandler::class,

        'emergency' => [
            'path' =>storage_path('logs/laravel.log'),

A driver regulated the channels. The driver will set what log data will be recorded into the system log file. There are lots of drivers built-in Laravel 9. You have to check Laravel 9 driver documentation for the driver list.

Now, write a log message in the Laravel application. We can pass a log message throw log data.

For that, we have to create a controller named “Logmessage”. Now, we need to run this command:

php artisan make:controllerLogmessage

After being created, it should look like this:

Now, we need to create a function in the controller:

class Logmessage extends Controller
    public function logtest()

Log::info(" Here is dummy log data");
        return view('welcome');

We use log::info to see the logmessage.

Process Three: Run and Test the System

Now, run and test the logging project.

We need to create a route for checking.

Next, we need to run the project and use the following command:

php artisan serve

Then, go to the route and log in to your application.

Before loading the URL, you can check under the storage directory.

There is no log file.

Once you load the URL, it will show the log file.

The URL will look like the following image:

Then, load the URL:

The Laravel.log file was created, and we will open the following log file:

Here, you can check all your application errors.


In this article, we discussed how Laravel logging was accomplished in three processes. The processes included installing Laravel 9 in the system, configuring log in the project, and running and testing the system. We hope this article will help you with your application activity.
