As the scale of web applications continues to expand, queues have become an essential part of various systems. Queues can improve application performance by processing certain tasks asynchronously. Many PHP developers use the Laravel framework, and Laravel provides a very useful queue management tool - Laravel Queues.
Laravel Queues allow developers to easily implement functions such as task dispatching and asynchronous task processing. We can configure different queue drivers, such as database driver, Redis driver, etc. In Laravel, we can also use a tool called Laravel Horizon to monitor and manage queues.
Laravel Horizon is a queue monitoring toolkit officially provided by Laravel. It provides an intuitive Dashboard to monitor the running status of the queue in real time, making it convenient for developers to manage and debug the queue. This article will introduce how to use Laravel Horizon to implement queue monitoring, and demonstrate its main functions and advantages.
1. Install Laravel Horizon
First, we need to install Laravel Horizon in our Laravel application. We can use Composer to install:
composer require laravel/horizon
After the installation is complete, we need to add the Laravel Horizon service provider in the config/app.php file. Open the config/app.php file and add:
LaravelHorizonHorizonServiceProvider::class,
Next, we need to generate Horizon configuration files and Horizon language packs in the providers array. We can use the Artisan command to generate:
php artisan vendor:publish --provider="LaravelHorizonHorizonServiceProvider"
2. Configure Laravel Horizon
After installing Laravel Horizon, we need to configure it. We can configure Horizon using the config/horizon.php configuration file. Through this file, we can configure the queue connection, the number of queue worker processes, log level, exit wait time, and other settings about the queue.
Where, connection is the name of the queue connection configured for Horizon monitoring. Laravel uses redis as the default queue driver by default, so we can set this name to "redis".
In the config/horizon.php file, we can set the Horizon access method, such as whether authentication is required. We can add the standard Laravel authentication middleware to Horizon's routes. This will ensure that only authenticated users can view Horizon's Dashboard page:
'middleware' => ['web', 'auth'],
3. Start Horizon
After installing and configuring Laravel Horizon, we can start Horizon. We can start Horizon using the Artisan command:
php artisan horizon
On our console window you will see details about Horizon. This includes the name of the queue to which Horizon is connected, the number of worker processes, log output, etc.
4. Using Laravel Horizon
After starting Horizon, we can access the Horizon Dashboard page. We can access it through the following URL:
http://your-app.com/horizon
On the Dashboard page, we can see a lot of queue-related data. These include:
- The number of "pending" tasks: Under the "pending" tab, we can see the number of unprocessed tasks in the current queue. This helps us understand the health of the queue in real time.
- Real-time metrics: Under the real-time metrics tab, we can view real-time metrics on completion, failed tasks, processing delays, etc. This tab helps us better understand the status of the queue.
- Worker Processes: Under the Worker Processes tab, we can view the list of running queue worker processes and can view information about each worker process. Here we can view the memory consumed by each process, the number of tasks processed, etc.
- Queue: Under the Queue tab, we can get more detailed information about the queue. We can view information about the queue's name, task type, task count, etc. Here we can also perform various actions such as liking, pausing and unliking the queue, as well as clearing the queue manually.
Summary
Laravel Horizon is a very practical and easy-to-use queue monitoring tool in the Laravel framework. With Horizon, we can better understand the status of the queue, process and ensure that tasks in the queue are processed in a fast and efficient manner. If you are using the Laravel framework, using Laravel Horizon is an excellent option to manage your queues.

Laravel stands out by simplifying the web development process and delivering powerful features. Its advantages include: 1) concise syntax and powerful ORM system, 2) efficient routing and authentication system, 3) rich third-party library support, allowing developers to focus on writing elegant code and improve development efficiency.

Laravel and Python have their own advantages and disadvantages in terms of performance and scalability. Laravel improves performance through asynchronous processing and queueing systems, but due to PHP limitations, there may be bottlenecks when high concurrency is present; Python performs well with the asynchronous framework and a powerful library ecosystem, but is affected by GIL in a multi-threaded environment.

Laravel is suitable for projects that teams are familiar with PHP and require rich features, while Python frameworks depend on project requirements. 1.Laravel provides elegant syntax and rich features, suitable for projects that require rapid development and flexibility. 2. Django is suitable for complex applications because of its "battery inclusion" concept. 3.Flask is suitable for fast prototypes and small projects, providing great flexibility.

Laravel can be used for front-end development. 1) Use the Blade template engine to generate HTML. 2) Integrate Vite to manage front-end resources. 3) Build SPA, PWA or static website. 4) Combine routing, middleware and EloquentORM to create a complete web application.

PHP and Laravel can be used to build efficient server-side applications. 1.PHP is an open source scripting language suitable for web development. 2.Laravel provides routing, controller, EloquentORM, Blade template engine and other functions to simplify development. 3. Improve application performance and security through caching, code optimization and security measures. 4. Test and deployment strategies to ensure stable operation of applications.

Laravel and Python have their own advantages and disadvantages in terms of learning curve and ease of use. Laravel is suitable for rapid development of web applications. The learning curve is relatively flat, but it takes time to master advanced functions. Python's grammar is concise and the learning curve is flat, but dynamic type systems need to be cautious.

Laravel's advantages in back-end development include: 1) elegant syntax and EloquentORM simplify the development process; 2) rich ecosystem and active community support; 3) improved development efficiency and code quality. Laravel's design allows developers to develop more efficiently and improve code quality through its powerful features and tools.
