Menampilkan Informasi CPU

Terkadang dalam melakukan konfigurasi server kita perlu mengetahui informasi detil CPU yang digunakan pada mesin sehingga konfigurasi dapat berjalan maksimal.

Ada beberapa cara untuk menampilkan informasi CPU, yang pertama:

server# sysctl -a | egrep -i 'hw.machine|hw.model|hw.ncpu'

output

hw.machine: amd64
hw.model: Intel(R) Xeon(R) CPU X3430 @ 2.40GHz
hw.ncpu: 4
hw.machine_arch: amd64

Mengambil informasi CPUINFO dari dmesg:

server# dmesg | grep -i cpu

atau

server# grep -i cpu /var/run/dmesg.boot

output

CPU: Intel(R) Xeon(R) CPU X3430 @ 2.40GHz (2394.00-MHz K8-class CPU)
