Cómo aplicar reinicios con una política de escalada progresiva

Antes de desplegar este script, asegúrate de que tu logotipo corporativo esté disponible en /var/root/CompanyAssets/logo.png en cada dispositivo gestionado. El script redimensiona y copia el logotipo a la carpeta de recursos de swiftDialog automáticamente. Usar el logotipo corporativo garantiza que los usuarios reconozcan las alertas como comunicaciones TI y no las descarten como ruido. Puedes distribuir el archivo usando la gestión de archivos de Applivery.

Una vez en el panel de Applivery, sigue los pasos descritos aquí para crear un script. Pega el siguiente script en el editor, selecciona Bash como lenguaje, dale un nombre descriptivo (por ejemplo, Política de reinicio forzado) y haz clic en Crear.
