Nut
NUT es un sistema de gestión de fuentes de alimentación ininterrumpida (SAI/UPS) que monitorea y controla el hardware de protección de energía. Funciona como un coordinador de apagado automatizado y un monitor de energía de red, implementando el estándar RFC 9271 para comunicarse con el hardware de energía.
El proyecto actúa como una capa de traducción de controladores de hardware, convirtiendo señales de interfaces USB, serie y SNMP en un formato de datos unificado. Emplea una arquitectura cliente-servidor para transmitir métricas de batería y voltaje desde los controladores de hardware a clientes de monitoreo remotos a través de una red.
Las capacidades incluyen monitoreo de energía en tiempo real, visualización del estado del hardware mediante paneles basados en web y la gestión de unidades de distribución de energía. El sistema también maneja apagados seguros automatizados basados en umbrales críticos de batería y proporciona herramientas para el descubrimiento de dispositivos y recuperación de reinicio de hardware.
La seguridad se gestiona mediante control de acceso basado en IP para comandos de servidor y la asignación de privilegios de acceso al hardware mediante reglas del sistema.
