\"How<\/p>\n

Ubuntu<\/a>, a popular Linux distribution, is widely used in various environments, from personal computers to VPS<\/a> and dedicated servers<\/a>.<\/p>\n

One of the key aspects of maintaining a healthy system is monitoring its performance. The Central Processing Unit (in short – CPU), being the heart of a web server<\/a>, plays a pivotal role in system performance. Thus, understanding how to check the CPU’s status and information is crucial for any Ubuntu user.<\/p>\n

In this guide, we will go through the various options to check CPU information on Ubuntu using the command line.<\/p>\n

Let’s get started!<\/p>\n

Step 1: Open the Terminal<\/h2>\n

The first step is to open the terminal on your Ubuntu machine. You can do this by clicking on the terminal icon or by using the keyboard shortcut “Ctrl + Alt + T”.<\/p>\n

Step 2: Check CPU Information Using the lscpu Command<\/h2>\n

The “lscpu” command displays the CPU information on your Ubuntu machine. To use this command, open a terminal and type the following command:<\/p>\n

\r\nlscpu\r\n<\/pre>\n
The output will display detailed information about the CPU, including the number of cores, clock speed, cache size, and other features.<\/p>\n
\r\nArchitecture:        x86_64\r\nCPU op-mode(s):      32-bit, 64-bit\r\nByte Order:          Little Endian\r\nCPU(s):              8\r\nOn-line CPU(s) list: 0-7\r\nThread(s) per core:  1\r\nCore(s) per socket:  1\r\nSocket(s):           8\r\nNUMA node(s):        1\r\nVendor ID:           GenuineIntel\r\nCPU family:          6\r\nModel:               106\r\nModel name:          Intel(R) Xeon(R) Gold 6336Y CPU @ 2.40GHz\r\nStepping:            6\r\nCPU MHz:             2399.998\r\nBogoMIPS:            4799.99\r\nVirtualization:      VT-x\r\nHypervisor vendor:   KVM\r\nVirtualization type: full\r\nL1d cache:           32K\r\nL1i cache:           32K\r\nL2 cache:            4096K\r\nL3 cache:            16384K\r\nNUMA node0 CPU(s):   0-7\r\n<\/pre>\n
Step 3: Check CPU Usage Using the top Command<\/h2>\n
The “top” command displays the real-time CPU usage on your Ubuntu machine. To use this command, open a terminal and type the following command:<\/p>\n
\r\ntop\r\n<\/pre>\n
The output will display a live view of the system processes, including CPU usage, memory usage, and other details. To exit the “top” command, press “q” on your keyboard.<\/p>\n

Step 4: Check CPU Temperature Using the lm-sensors Package (Optional)<\/h2>\n
The “lm-sensors” package is a command-line tool that can be used to monitor the temperature sensors on your Ubuntu machine, including the CPU temperature. To install “lm-sensors”, open a terminal and type the following command:<\/p>\n
\r\nsudo apt-get install lm-sensors\r\n<\/pre>\n
Once installed, you can use the “sensors” command to display the CPU temperature. To use this command, open a terminal and type the following command:<\/p>\n
\r\nsensors\r\n<\/pre>\n
The output will display the temperature sensors on your Ubuntu machine, including the CPU temperature.<\/p>\n
