php - Laravel 日志系统与 Logstash

Question

我有一个 Laravel 应用程序，我想将日志存储到 Logstash 中并在 kibana 中查看它们，我在网上搜索了很多以找到解决方案，但我没有找到任何好的来源，是否有任何包使用 laravel 登录logstash ??? 顺便说一句，我的 Logstash 和 kibana 运行没有任何问题，我现在只需要一个数据源。 这是我正在运行的 elstic 搜索:

    {
name: "5351ced3b7a4",
cluster_name: "elasticsearch",
cluster_uuid: "Ej5TRN8CQyGvemZlT3gAFA",
version: {
number: "7.1.1",
build_flavor: "oss",
build_type: "tar",
build_hash: "7a013de",
build_date: "2019-05-23T14:04:00.380842Z",
build_snapshot: false,
lucene_version: "8.0.0",
minimum_wire_compatibility_version: "6.8.0",
minimum_index_compatibility_version: "6.0.0-beta1"
},
tagline: "You Know, for Search"
}

编辑 正如答案解释了我所做的那样，现在我在 laravel 的日志中收到此错误:

[2019-08-05 14:16:17] laravel.INFO: Hello logstash!  

编辑: 日志配置文件:

<?php

use Monolog\Handler\StreamHandler;
use Monolog\Handler\SyslogUdpHandler;

Answer 1

如 this post 中所述这很容易做到。

1. 在 config/logging.php 中配置日志记录 channel ( docs )

    'channels' => [
        // ... other channels like stack or single
        'logstash' => [
            'driver' => 'custom',
            'via'    => \App\LogstashLogger::class,
            'host'   => env('LOGSTASH_HOST', '127.0.0.1'),
            'port'   => env('LOGSTASH_PORT', 4718),
        ],
    ],

创建自定义 Logger 工厂 ( docs )

namespace App;

use Monolog\Formatter\LogstashFormatter;
use Monolog\Handler\SocketHandler;
use Monolog\Logger;
use Psr\Log\LoggerInterface;
class LogstashLogger {
    /**
     * @param array $config
     * @return LoggerInterface
     */
    public function __invoke(array $config): LoggerInterface
    {
        $handler = new SocketHandler("udp://{$config['host']}:{$config['port']}");
        $handler->setFormatter(new LogstashFormatter(config('app.name')));
        return new Logger('logstash.main', [$handler]);
    }
}

这将使用 monolog logstash formatter 通过 udp 将日志写入指定的主机和端口

现在要将日志条目写入logstash，请指定您刚刚创建的日志记录 channel ( docs )

Log::channel('logstash')->info('Hello logstash!');
