Monolog get requested url and simple log on in Laravel 5 - php

Question

I have checked the official repo of monolog and put together below code, its working great and I am getting response in Slack. But the response are very verbose, How Can i get simple response, without Stack Trace.
And as suggested on doc I have added $monolog->pushProcessor(new WebProcessor($_SERVER)); but its not giving any information about requested URL and server.
class AppServiceProvider extends ServiceProvider {
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
if ($this->app->environment('production')) {
// Get The Logger
$monolog = Log::getMonolog();
// **********************************************************************************************
// I have tried official WebProcessor to get url, but its not giving me anything
// **********************************************************************************************
$monolog->pushProcessor(new WebProcessor($_SERVER));
$monolog->pushProcessor(function ($record) {
$record['extra']['session_id'] = Cookie::get(config('session.cookie'));
$record['extra']['request_id'] = Session::get('request_id');
return $record;
});
$slackHandler = new SlackHandler(env('SLACK_TOKEN'), '#sss-sslogs', 'sss-log', true, ':warning:', Logger::ERROR);
// **********************************************************************************************
// Setup Line Formatter but no luck
// **********************************************************************************************
// the default date format is "Y-m-d H:i:s"
$dateFormat = "Y n j, g:i a";
// the default output format is "[%datetime%] %channel%.%level_name%: %message% %context% %extra%\n"
$output = "%datetime% > %level_name% > %message% %context% %extra%\n";
// finally, create a formatter
$formatter = new LineFormatter($output, $dateFormat);
$slackHandler->setFormatter($formatter);
$monolog->pushHandler($slackHandler);
}
}
Above code is giving me below response in Slack channel
