title: Laravel log level, how is different?
body: <p>I can see few log options in Laravel 5.4 such as</p>
  
  <pre><code>Log::emergency($message);
  Log::alert($message);
  Log::critical($message);
  Log::error($message);
  Log::warning($message);
  Log::notice($message);
  Log::info($message);
  Log::debug($message);
  </code></pre>
  
  <p>And I can change log level in <code>app.php</code> at <code>'log_level' =&gt; env('APP_LOG_LEVEL', 'debug'),</code> to any kind of level I want.</p>
  
  <p>But I was wondering that, what is different? What kind of log has been wirtten when one of <code>critical, alert, emergency</code> is selected?</p>
