laravel8のログ出力でログの出力先を変更し、別ファイルへログを出力する方法について。ログについての詳細は本家。
プロジェクト作成とサンプルクラス作成
まずプロジェクトを作成する。
$ composer create-project laravel/laravel sandbox --prefer-dist
$ cd sandboxログ出力確認用のコマンドクラスを生成する。
$ php artisan make:command SampleLogBatchログ出力設定の追記
デフォルトのログ設定ファイルを編集する。
$ vi app/config/logging.php中身は以下。追記部分にコメントあり。
<?php
use Monolog\Handler\NullHandler;
use Monolog\Handler\StreamHandler;
use Monolog\Handler\SyslogUdpHandler;
return [
/*
|--------------------------------------------------------------------------
| Default Log Channel
|--------------------------------------------------------------------------
|
| This option defines the default log channel that gets used when writing
| messages to the logs. The name specified in this option should match
| one of the channels defined in the "channels" configuration array.
|
*/
'default' => env('LOG_CHANNEL', 'stack'),
/*
|--------------------------------------------------------------------------
| Log Channels
|--------------------------------------------------------------------------
|
| Here you may configure the log channels for your application. Out of
| the box, Laravel uses the Monolog PHP logging library. This gives
| you a variety of powerful log handlers / formatters to utilize.
|
| Available Drivers: "single", "daily", "slack", "syslog",
| "errorlog", "monolog",
| "custom", "stack"
|

'channels' => [
'stack' => [
'driver' => 'stack',
'channels' => ['single'],
'ignore_exceptions' => false,

// 今回このブロックを追加
'sample-log'=>[
'driver'=>'single',
'level'=>'debug',
'path'=>storage_path('logs/sample-log.log'),
],
],
];
実行クラスの編集
生成したコマンドクラスを編集してログを追記する。
$ vi app/Console/Commands/SampleLogBatch.php <?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use Illuminate\Support\Facades\Log;
class SampleLogBatch extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'batch:sample-log';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Log Output Sample';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return int
*/
public function handle()
{
// いろいろなログ種別で出力してみる
Log::channel('sample-log')->debug('sample log debug');
Log::channel('sample-log')->info('sample log info');
Log::channel('sample-log')->notice('sample log notice');
Log::channel('sample-log')->warning('sample log warning');
Log::channel('sample-log')->error('sample log error');
Log::channel('sample-log')->critical('sample log critical');
Log::channel('sample-log')->alert('sample log alert');
Log::channel('sample-log')->emergency('sample log emergency');
return 0;
}
}
ログ出力の実行
コマンドを実行。
$ php artisan batch:sample-log実行後にログが出力されているか確認する。
$ ls storage/logs/
laravel.log sample-log.logログの中身も確認する。
$ cat storage/logs/sample-log.log
[2021-03-07 01:05:07] local.DEBUG: sample log debug
[2021-03-07 01:05:07] local.INFO: sample log info
[2021-03-07 01:05:07] local.NOTICE: sample log notice
[2021-03-07 01:05:07] local.WARNING: sample log warning
[2021-03-07 01:05:07] local.ERROR: sample log error
[2021-03-07 01:05:07] local.CRITICAL: sample log critical
[2021-03-07 01:05:07] local.ALERT: sample log alert
[2021-03-07 01:05:07] local.EMERGENCY: sample log emergency 処理によってログの出力を変えるのはよくある事なので、うまく使おう。
