Get server hardware details for ubuntu server

Question

I want to know what is command which will show me servers hardware [through ssh access], like how much Gb RAM is installed, cpu speed, and so on.

Thank You.

Solution 1

quick and dirty way:

cat /proc/meminfo

cat /proc/cpuinfo

Solution 2

lshw

I have found lshw to be an invaluable resource in gathering hardware information that is otherwise difficult to gather without cracking the servers case (BIOS version, Motherboard model number, which slots of RAM are populated, etc)

A good writeup/overview of lshw can be found here

Solution 3

• lshw
• lspci
• lsusb
• lsscsi
• dmidecode

Solution 4

More specific information about hardware may be given by a dmidecode command.

Solution 5

Can do that Ansible if you have Python2 and SSH access on a remote machine.

ansible -m setup ${hostname}

This will output a nice JSON which includes CPU/RAM/HDD/Network and software configuration. Read the documentation for more information.
