+Data Storage
+-----
+
+You can save debug data in any storage, for this you need to implement the yii\debug\components\data\DataStorage interface, and configure the module.
+Solves the problem of correct operation of the debug panel in case the application is located on several servers.
+
+```php
+return [
+    'bootstrap' => ['debug'],
+    'modules' => [
+        'debug' => [
+            'class' => 'yii\debug\Module',
