请问Monolog记录到mongodb该如何配置

return [
    'default' => [
        'handlers' => [
            [
                'class' => Monolog\Handler\MongoDBHandler::class,
                'constructor' => [
                    new \MongoDB\Client('mongodb://localhost:27017'),
                    'test',
                    'logs',
                    Monolog\Logger::DEBUG,
                ],
            ],
        ],
    ],
];
