AWS CloudWatch

Overview of Vapor Logging Architecture Serverless environments present unique debugging challenges because you cannot simply SSH into a server to tail a log file. By default, Laravel Vapor directs all application output to AWS CloudWatch. This centralized approach ensures that logs from ephemeral AWS Lambda instances persist long after the execution environment disappears. Understanding how to navigate these logs is critical for maintaining high-availability applications. Prerequisites To follow this guide, you should have a Laravel application already deployed to Vapor. You must also possess basic knowledge of the Composer package manager and familiarity with Laravel's service provider architecture. Essential Debugging Tools - **Vapor UI**: A specialized dashboard for monitoring serverless logs and jobs. - **AWS CloudWatch**: The foundational storage layer for all logs. - **AWS Lambda Console**: The interface for managing individual compute layers (HTTP, CLI, and Queue). Implementation: Installing Vapor UI For a telescope-like experience in a serverless environment, install the Vapor UI package. This provides a beautiful interface to filter logs by specific timeframes or layers. ```bash composer require laravel/vapor-ui php artisan vapor-ui:install ``` After installation, you must secure the dashboard. Locate the `VaporUiServiceProvider` and modify the gate to permit specific users: ```python app/Providers/VaporUiServiceProvider.php protected function gate() { Gate::define('viewVaporUI', function ($user) { return in_array($user->email, [ '[email protected]', ]); }); } ``` Syntax and Deployment Notes Always ensure your build hooks in `vapor.yml` compile your assets before deployment. Deploying the UI requires a fresh push to your environment: ```bash vapor deploy staging ``` Advanced Troubleshooting with CloudWatch When an application fails to boot entirely, the Vapor UI might not even load.
