 ## Агенты VM и LXC

-Read-only агент показывает состояние Linux внутри VM/LXC: load average, память,
-корневой раздел, uptime, версию агента, Docker-контейнеры, health-check и число
-перезапусков. Агент сам подключается к Dashboard каждые 10 секунд; открывать
-входящий порт внутри гостевой системы не нужно.
+Read-only агент показывает состояние Linux внутри VM/LXC: CPU, load average,
+память, корневой раздел, uptime, ОС, ядро, IP-адреса, systemd-службы, доступные
+APT-обновления и необходимость перезагрузки. Для Docker отображаются контейнеры,
+health-check, число перезапусков, CPU и память. Агент сам подключается к Dashboard
+каждые 10 секунд; открывать входящий порт внутри гостевой системы не нужно.
+
+В подробностях агента systemd-службы разделяются на системные, установленные
+дополнительно и локальные unit-файлы. Для каждой службы показываются пакет и путь
+unit-файла, время запуска, число перезапусков, последний exit code, память и
+накопленное CPU-время, когда соответствующий accounting доступен в systemd.

 Откройте `Настройки → Агенты`, укажите адрес Dashboard, доступный из VM/LXC, и
 VMID. Кнопка создаст готовую команду установки. Одноразовый токен действует 15
 минут и после регистрации заменяется индивидуальным секретом агента.

+После однократной установки агент обновляется автоматически вслед за Dashboard.
+Центральный сервер отдаёт агенту собственный бинарник и SHA-256; агент проверяет
+контрольную сумму, атомарно заменяет файл и перезапускается через systemd. Если
+агент был удалён из Dashboard, повторная команда с новым токеном автоматически
+выполнит новую регистрацию.
+
 В первой версии агент не выполняет команды и не перезапускает службы или
 контейнеры. Для чтения Docker ему требуется доступ к `/var/run/docker.sock`,
 поэтому служба устанавливается от root. Сам Dashboard пока не имеет
 авторизации: используйте локальную сеть или HTTPS через доверенный reverse
 proxy и не публикуйте агентские API напрямую в интернет.

+Полностью удалить агент из VM/LXC:
+
+```bash
+curl -fsSL https://git.myown.center/maxim/ProxmoxDash/raw/branch/main/scripts/uninstall-agent.sh | sh
+```
+
+Оформление, пороги, почта и обновления Dashboard находятся в обычных настройках.
+Рабочие инструменты — сервисы, агенты, плановые работы и UPS-сценарий — вынесены
+в отдельный раздел `Управление` в шапке Dashboard.
