laravel - Laravel Vapor 自定义日志以 JSON 格式记录到 Amazon AWS Cloudwatch

Question

默认情况下，Laravel Vapor 将laravel.log文件推送到 strerr 输出。这是 Lambda 拾取并扔给 Cloudwatch 的。除非您通过 Vapor UI 进行查看，否则很难查看。寻找一种简单的方法来执行此操作并将它们直接推送到 Cloudwatch（带有多个文件）。

Answer 1

首先添加了这个很棒的库

composer require maxbanton/cwh 

然后将此添加到您的日志配置中...

        'cloudwatch' => [
            'driver' => 'custom',
            'via' => \App\Logging\CloudWatchLoggerFactory::class,
            'formatter' => Monolog\Formatter\JsonFormatter::class,
            'cloudwatch_stream_name' => 'laravel',
            'sdk' => [
                'region' => 'eu-west-1',
                'version' => 'latest',
                'credentials' => [
                    'key' => env('AWS_CW_ACCESS'),
                    'secret' => env('AWS_CW_SECRET')
                ]
            ],
            'retention' => 730,
            'level' => 'debug',
        ],

您需要为有权访问 Cloudwatch 的 IAM 用户添加密钥AWS_CW_ACCESS。AWS_CW_SECRET

然后添加App/Logging/CloudWatchLoggerFactory.php以下内容..

<?php

namespace App\Logging;

use Aws\CloudWatchLogs\CloudWatchLogsClient;
use Maxbanton\Cwh\Handler\CloudWatch;
use Monolog\Formatter\JsonFormatter;
use Monolog\Logger;

class CloudWatchLoggerFactory
{
    /**
     * Create a custom Monolog instance.
     *
     * @param  array  $config
     * @return \Monolog\Logger
     */
    public function __invoke(array $config)
    {
        $sdkParams = $config["sdk"];
        $tags = $config["tags"] ?? [ ];
        $name = $config["name"] ?? 'cloudwatch';
        
        // Instantiate AWS SDK CloudWatch Logs Client
        $client = new CloudWatchLogsClient($sdkParams);
        
        // Log group name, will be created if none
        $groupName = config('app.name') . '-' . config('app.env');

        // Log stream name, will be created if none
        // $streamName = config('app.hostname');
        $streamName = $config["cloudwatch_stream_name"];

        // Days to keep logs, 14 by default. Set to `null` to allow indefinite retention.
        $retentionDays = $config["retention"];
        // Instantiate handler (tags are optional)
        $handler = new CloudWatch($client, $groupName, $streamName, $retentionDays, 10000, $tags);
        $handler->setFormatter(new JsonFormatter());
        // Create a log channel
        $logger = new Logger($name);
        // Set handler
        $logger->pushHandler($handler);
        //$logger->pushProcessor(new CompanyLogProcessor()); //Use this if you want to adjust the JSON output using a log processor
        return $logger;
    }
}

然后，您可以将其用作任何日志...即Log::channel('cloudwatch')->info('hey');

要强制默认 laravel.log 到这里并显示在蒸汽中，只需将其添加为堆栈

        'vapor' => [
            'driver' => 'stack',
            'channels' => ['stderr', 'cloudwatch'],
            'ignore_exceptions' => false,
        ],

然后在你的环境变量中设置logging.default设置vapor。

如果您想要其他记录通道，只需cloudwatch使用新通道复制通道设置并确保调整cloudwatch_stream_name.

感谢我在 Stackoverflow 上找到的另一个答案，帮助我到达了这里。我想直接在 Laravel Vapor 的答案下记录这个，因为我想很多其他人会在尝试这样做时遇到困难！
