Why is this the accepted answer when an earlier answer provided a faster builtin solution? This answers questions that weren't even asked.
@deanresin I completely agree with you. But if you know how to use htop then you will know how to monitor each CPU core performance. Thank you.
In your dash i.e. pressing
superkey search for system monitor application.
If you are comfortable with command line there are tools like
htopwhere cpu usage can be viewed as well.
gnome-system-monitor is not installed by default on Ubuntu 18.04 anymore for some reason, you need `sudo apt install gnome-system-monitor` first: http://releases.ubuntu.com/18.04/ubuntu-18.04.3-desktop-amd64.manifest
As said in previous answer you can use system monitor which is the best tool. If you want more information you can try some commands on terminal
top- its a command to see all the processes and their CPU usage. Just read the screen carefully and you would find lot of other useful information there. you can press Ctrl+c to close it.
Or you can also try
cat /proc/cpuinfo- for other information about cpu
