Dmidecode - собираем информацию о "начинке" сервера

Опубликовано muff в Ср, 2012-01-18 04:46

Понадобилось как-то узнать подробно, из каких комплектующих собран удаленный сервер, работающий под управлением FreeBSD. Вывода /var/run/dmesg.boot в моем случаем было явно недостаточно... В таких ситуациях на помощь приходит утилита dmidecode. С ее помощью можно получить детальную информацию о материнской плате, процессоре, оперативной памяти и тд.

Установка утилиты выполняется из системы портов и проблем не вызывает:

# cd /usr/ports/sysutils/dmidecode && make install clean && rehash

По завершению установки (которая, кстати, выполняется довольно шустро) советую ознакомиться со страницами руководства:

# man dmidecode

Ну и, собственно, теперь можно "пожинать плоды". Вывод информации о "железе" (обрезал вывод, поскольку вывод информации предоставляется довольно много):

# dmidecode | less

# dmidecode 2.11
SMBIOS 2.3 present.

Как видите, информация довольно обширная. Чтобы конкретизировать получаемую инфорамацию, необходимо указывать соответствующие ключи. Ключи можно узнать на странице man-руководства. Например, чтобы вывести информацию о процессорах (в моем случае их два). Пример такого запроса:

Теперь дело за малым - "повыдергивать" из вывода dmidecode необходимую информацию.
