+      ⏱️  Общее время установки: {{ total_wait_time }} секунд
+      📊 Статус компонентов:
+        • Служба: ✅ {{ grafana_active.stdout }}
+        • Порт 3000: {{ '✅ открыт' if port_check is defined and port_check.state == 'started' else '❌ закрыт' }}
+        • API: {{ '✅ доступен (HTTP ' ~ api_check.status ~ ')' if api_check is defined and api_check.status == 200 else '❌ недоступен' }}
+      
+      🔗 Доступ:
+        • URL: http://{{ inventory_hostname }}:3000
+        • Логин: admin
+        • Пароль: {{ grafana_admin_password | default('admin') }}
+      
+      📋 Для проверки выполните:
+        curl http://{{ inventory_hostname }}:3000/api/health
+      
+      💡 Примечание: Первый запуск Grafana занимает время из-за:
+        1. Миграций базы данных
+        2. Установки плагинов по умолчанию
+        3. Инициализации сервиса
+      
+      Последующие запуски будут значительно быстрее.
