Laravel 5.6 aws cloudwatch 日志

Laravel 5.6与亚马逊AWS CloudWatch日志的集成为我们提供了一个强大的工具，用于管理和监控我们的应用程序日志。通过将Laravel与AWS CloudWatch结合使用，我们可以轻松地将我们的应用程序日志发送到云端，并通过CloudWatch的强大功能进行实时监控和分析。本文将介绍如何使用Laravel 5.6和AWS CloudWatch来管理和监控应用程序日志，并提供一些实际案例代码供参考。

shell
composer require aws/aws-sdk-php

        ],
    ],
    'retention' => 30, // 设置日志保留时间，单位为天
    'group_name' => 'laravel-app', // 设置日志组名称
    'stream_name' => 'laravel-app-stream', // 设置日志流名称
