python-hwinfo : Display Summary Of Hardware Information Using Standard Linux Utilities

Till the date, we have covered most of the utilities which discover Linux system hardware information & configuration but still there are plenty of commands available for the same purpose.

In that, some of the utilities are display detailed information about all the hardware components and reset will shows only specific device information.

In this series, today we are going to discuss about python-hwinfo, it is one of the tool that display summary of hardware information and it’s configuration in the neat way.

What’s python-hwinfo

This is a python library for inspecting hardware and devices by parsing the outputs of system utilities such as lspci and dmidecode.

It’s offering a simple CLI toll which can be used for inspect local, remote and captured hosts. Run the command with sudo to get maximum information.

Additionally you can execute this on remote server by providing a Server IP or Host name, username, and password. Also you can use this tool to view other utilities captured outputs like demidecode as ‘dmidecode.out’, /proc/cpuinfo as ‘cpuinfo’, lspci -nnm as ‘lspci-nnm.out’, etc,.

How to Use python-hwinfo in local machine

Execute the following command to inspect the hardware present on a local machine. The output is much clear and neat which i didn’t see in any other commands.

It’s categorized the output in five classes.

  • Bios Info: It’s contains bios_vendor_name, system_product_name, system_serial_number, system_uuid, system_manufacturer, bios_release_date, and bios_version
  • CPU Info: It’s display no of processor, vendor_id, cpu_family, model, stepping, model_name, and cpu_mhz
  • Ethernet Controller Info: It’s shows device_bus_id, vendor_name, vendor_id, device_name, device_id, subvendor_name, subvendor_id, subdevice_name, and subdevice_id
  • Storage Controller Info: It’s shows vendor_name, vendor_id, device_name, device_id, subvendor_name, subvendor_id, subdevice_name, and subdevice_id
  • GPU Info: It’s shows vendor_name, vendor_id, device_name, device_id, subvendor_name, subvendor_id, subdevice_name, and subdevice_id
$ sudo hwinfo
