If that’s a problem, you can look into other options like htop (for CPU usage stats) or lm_sensors with any frontend (for CPU temperature readings). The main downside to Glances is that it’s not lightweight. It’s a feature-rich program that allows you remotely monitor a machine via a web or CLI interface. This is generally enough, but if you want in-depth CPU data or temperature stats, you’ll need a more advanced utility like Glances. It’ll let you monitor the overall CPU usage, utilization per thread, as well as usage % per process. The built-in System Monitor is a good option if you want a simple graphical app. If you’re trying to monitor your system’s CPU usage and temperature stats in real-time, you’ll need some different tools. You’ll find detailed info on each thread there. As we’re looking for CPU data specifically, go to the Devices > Processor section.

The node is a unique small identifier identifying a NUMA node.

The processor is a unique small integer identifying a CPU.

sudo apt install hardinfoĪfter installing it, you can search ‘System Profiler’ in the Applications menu, or launch it from the terminal by entering hardinfoĪs stated, hardinfo can display info on most aspects of your system from the OS, kernel, and users to hardware components. The getcpu () system call identifies the processor and node on which the calling thread or process is currently running and writes them into the integers pointed to by the cpu and node arguments. It’s a lightweight app that displays hardware and OS info in a GTK+ window. But I’ve already covered multiple CLI tools, I’ll recommend hardinfo instead in this section. There are plenty of great third-party system monitors like cpuid or hwinfo. sudo dmidecode -type processor Use Third-Party Tools Even when there’s overlap with the other tools, dmidecode’s output tends to be easier to understand. It displays some additional info compared to other tools such as the processor ID, current frequency, voltage, etc. cat /proc/cpuinfo Use dmidecodeĭmidecode is used to get hardware info by translating the SMBIOS into human-readable form. So, needless to say, you can directly read this file to display detailed info for each thread. Specifically, the /proc/cpuinfo file is where utilities like lscpu get the majority of CPU info from. The /proc/ directory contains files that detail the current state of the kernel and running processes. This includes the model name, threads, cores, sockets, frequency, cache info, and so on. It gathers the info from sources like sysfs and /proc/cpuinfo and displays everything you could ask for. Lscpu is the defacto default command for getting CPU info on Ubuntu. If you’re looking to monitor the CPU stats in real time instead, we’ll cover the best utilities for that purpose as well. But this is CPU usage from startup, not real-time usage.Ubuntu supports numerous tools for checking the CPU architecture info from built-in ones like lscpu to third-party tools like hardinfo.

Here, process uses per process are displayed (only a part). I used the vmstat command, and I only want the 'sy' number in the cpu colon.

There's a solution using 'grep' or 'awk' or something like that. I want to retrieve percentage processor usage but no other commands that show tons of numbers.
