DMIDecode - Command dmidecode

Parses the output of the dmidecode command to catalogue the hardware associated with the system.

In general, DMIdecode recognizes the sections of device information, separated by blank lines, processed in the following way.

  • It uses the descriptor line that precedes the indented device information (e.g. ‘BIOS Information’) as the name for that section, converting the name into lower case and replacing spaces with underscores (e.g. ‘bios_information’) to look more Pythonic.

  • Within each section, data is split up on colons.

  • Lines such as ‘Characteristics’ that end with a colon and have one or more further indented lines after them are converted into a list of the values so indented.

The common information retrieved from dmidecode is available in several convenience properties:

  • system_info - Information about the machine itself

  • bios - the BIOS information

  • bios_vendor - the BIOS’s ‘Vendor’ attribute

  • bios_date - the BIOS’s ‘Release Date’ attribute

  • processor_manufacturer - the processor’s ‘Manufacturer’ attribute

  • is_present - this indicates whether dmidecode information was found.
