+Центр уведомлений объединяет критические события, предупреждения и
+информационные сообщения по CPU, памяти, storage, SMART, ZFS, UPS, VM/LXC и
+резервным копиям. Критические события всегда отображаются первыми.

 На главном экране находятся компактные карточки CPU, памяти, диска и сети.
 Нажатие на карточку открывает подробные показатели.
