一个零碎须要继续优化,日志尤为要害。通过巧用中间件记录零碎的慢申请,能够不必依赖任何监控型服务,定期剖析日志,从而优化零碎。
通过定义一个监控中间件,记录慢查问。
<?php
namespace ModStart\Core\Monitor;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Log;
class ModStartMonitorMiddleware
{public function handle(Request $request, \Closure $next)
{$response = $next($request);
if (defined('LARAVEL_START')) {$time = round((microtime(true) - LARAVEL_START) * 1000, 2);
$param = json_encode(\Illuminate\Support\Facades\Request::input());
$url = $request->url();
$method = $request->method();
if ($time > 1000) {Log::warning("LONG_REQUEST $method [$url] ${time}ms $param");
}
}
return $response;
}
}
如果常量 LARAVEL_START 未定义可在入口文件中定义。
define('LARAVEL_START', microtime(true));
在零碎 Kernel 类中减少中间件到所有申请。
<?php
namespace App\Http;
class Kernel extends \Illuminate\Foundation\Http\Kernel
{
protected $middleware = [
\ModStart\Core\Monitor\ModStartMonitorMiddleware::class,
// ...
];
}
这样就能够在日志中看到慢申请
