Linux: finding System Hardware Information – Manufacturer, Model/Product Name, Serial Number and Physical Sockets, Processors/CPUs, Cores

Finding Hardware Manufacturer, Model/Product Name, Serial Number:

[root@ProdDB01 ~]# dmidecode -t system
# dmidecode 2.7
SMBIOS 2.3 present.

Handle 0x0100, DMI type 1, 25 bytes.

Finding Physical Sockets, Processors, Model, Cores:

You can find all of the details about system processor from below file location: Use grep to find the specific details

less /proc/cpuinfo

Physical Sockets (Processor Slots on the Mother board of a Computer):

[root@ProdDB01 ~]# dmidecode -t processor | grep -i "Socket Designation"
Socket Designation: Node 1
Socket Designation: Node 2
[root@ProdDB01 ~]#

[root@ProdDB01 ~]# grep "physical id" /proc/cpuinfo | sort -u | uniq | wc -l

2

[root@ProdDB01 ~]#

The number of “Physical Cores per Socket”:

[root@ProdDB01 ~]# grep "cpu cores" /proc/cpuinfo |sort -u |cut -d":" -f2

2

[root@ProdDB01 ~]#

The number of overall Cores (that appear logically to the OS):

[root@ProdDB01 ~]# cat /proc/cpuinfo | egrep "core id|physical id" | tr -d "n" | sed s/physical/\nphysical/g | grep -v ^$ | sort | uniq | wc -l
4
[root@ProdDB01 ~]#

Or

[root@ProdDB01 ~]# grep -c "processor" /proc/cpuinfo

4

[root@ProdDB01 ~]#
