AWSにデプロイしたLaravelのログを見やすくした

Posted at

はじめに

ECSにLaravelをデプロイしているときにCloudWatchLogsにログを吐いていたが
不具合が起こったときに調査しやすくするためにlogをjson化してなおかつ
同一リクエストのログをまとめて取得したかった

前提

ECSにデプロイしているALBを使用している時

コード

ALBを経由したリクエストにはX-Amzn-Trace-Idというヘッダーに
リクエストごとに固有のIDが振られるのでログに吐いておくと
あとで確認しやすい

app/Log/JsonFormatter.php
<?php

declare(strict_types=1);

namespace App\Log;

use Illuminate\Http\Request;
use Monolog\Formatter\NormalizerFormatter;

class JsonFormatter extends NormalizerFormatter
{
    /**
     * {@inheritdoc}
     */
    public function format(array $record)
    {
        $request = resolve(Request::class);
        $output = [];
        $output['level'] = $record['level_name'];
        $output['xAmznTraceId'] = $request->header('X-Amzn-Trace-Id');
        $output['message'] = $record['message'];
        foreach ($record['context'] as $var => $val) {
            $output[$var] = $val;
        }

        return json_encode($output, JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES) . PHP_EOL;
    }
}

phpコンテナの出力はstderrに出てくるので
logging.phpを以下のように修正

config/logging.php
       'stderr' => [
            'driver'    => 'monolog',
            'handler'   => StreamHandler::class,
            'formatter' => \App\Log\JsonFormatter::class,
            'with'      => [
                'stream' => 'php://stderr',
            ],
        ],
