Sysinfo - собираем информацию о удаленном сервере
Продолжая тему утилит для сбора информации о "железе", рассмотрим такой инструмент как sysinfo. Установку утилиты выполним из системы портов:
| # cd /usr/ports/sysutils/sysinfo && make install clean && rehash |
Утилита совместима с dmidecode и portaudit, однако для чистоты эксперимента отказался от интеграции с этими иснтрументами.
Установка завершена... Перед запуском советую ознакомиться с возможностями утилиты:

# sysinfo help SysInfo v1.0.1 by Daniel Gerzo for FreeBSD Operating System Usage: sysinfo [-a] [-c] [-d] [-h] [-v] [-v [level]] module ... The configuration variables can be set in the /usr/local/etc/sysinfo.conf file. |
Что ж... Посмотрим на результаты диагностики, чтобы оценить "возможности " утилиты.

Рано или поздно, но утилита должна пригодится, как рбочий интструмент. Хотя, чесно говоря, ожидал больше информации о аппаратной части сервера. Но этот недостаток компенсируется с лихвой информацией о софтварной части.
