      📊 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.
