How to check hardware information (CPU/MEM/Disk/PCIE card) by command under linux


How many physical cpu install
# cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
2

Cpu core number 
# cat /proc/cpuinfo| grep "cpu cores"| uniq
cpu cores : 2

# cat /proc/cpuinfo| grep "cpu cores"| uniq | awk {'print $4'}

2

Total CPU logical core

# cat /proc/cpuinfo| grep "processor"| wc -l

4

CPU model

#cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

      4  Intel(R) Xeon(R) Platinum 8170 CPU @ 2.10GHz

# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c |  awk {'print $5'}

8170

CPU code name

#cat /sys/devices/cpu/caps/pmu_name

Skylake , Haswell

CPU TDP (Need PTU linux tool)

./ptumon -s | grep -i "package tdp" | awk {'print$4'}

CPU turbo frequency
#dmidecode | grep -I "max speed" | tr -d "\n" | awk {'print$3'}

memory brand:

#dmidecode -t memory | grep -i manufacturer | tr -d "\n" | awk {'print$2'}

memory model

#dmidecode -t memory | grep -i part | tr -d "\n" | awk {'print$3'}

memory single size 

#dmidecode -t memory | grep -i size | tr -d "\n" | awk {'print$2'}

memory speed

#dmidecode -t memory | grep -i speed | tr -d "\n" | awk {'print$2'}

memory type & speed

# lshw | grep -i *-bank:0 -A 2 | sed '2!d' | awk {'print$3"-"$5'}

DDR4-2666

memory total size

#lshw -class memory | grep -i "system memory" -A 5 | sed '4!d' | awk {'print$2'}

memory slots

#midecode -t memory | grep -i part | wc -l 

Disk model
#lsblk --nodeps -o model | sed '2!d'  

Detail disk information
#smart -a /dev/yourdrive

Disk IO performance
#iostat -m

PCIE card 
# lspci | grep -i ethernet ; lspci | grep -i raid ; lspci | grep -i vga
