+### Configuration
+
+If you want to use it in a production environment, you can control whether or not to log a query via the configuration file：
+
+*config/logging.php:*
+
+```php
+return [
+    //...
+    'query' => [
+        'enabled' => env('LOG_QUERY', false),
+         
+        // Only record queries that are slower than the following time
+        // Unit: milliseconds
+        'slower_than' => 0, 
+    ],
+];
+```
