Is there a way to start system monitor app, from the console ?? I am not talking about terminal. I am talking about Ctrl + Alt + F1 mode

Plenty of command line options in [System Monitoring Tools For Ubuntu](https://askubuntu.com/q/293426/158442) – muru Oct 31 '17 at 05:36

you can use htop also and its more featured than top .
if you want to test it , then you have install it with
sudo apt-get install htop
after that type htop .

Depending on what your interested in, you might also want a specilized monitoring tool like iptraf, to monitor network traffic (very useful on a router) – alci Sep 22 '12 at 15:23

For a lot more detail about `htop` you can look at this answer: https://askubuntu.com/questions/787642/system-monitor-doesnt-accurately-show-memory-usage/971157#971157 – SDsolar Oct 31 '17 at 05:42
You can try the top command to have a system monitor in console. It will display the CPU usage for the processes running in your machine.
Another alternative is conky-cli. You can install it with the command
sudo apt-get install conky-cli
or using the link conky-cli 
After installation, start it with conky command.
One option is to use dstat
sudo apt-get update
sudo apt-get install dstat
then run it by simply entering
dstat
to get this default output which updates every second and provides column headers with every screenful:
The advantage dstat has over htop is the same that System-Monitor has, namely that it shows trends.
dstat is very versatile. Here is an article that explains the command line switches and shows some of the advanced options:

After writing this post I discovered that it works well to use Xming with PuTTY to get an X11 terminal over ssh - not on point of the question, but useful info even though the character terminal is much, much faster: https://askubuntu.com/questions/971171/how-to-use-putty-to-get-x11-connections-over-ssh-from-windows-to-ubuntu/971172#971172 – SDsolar Oct 31 '17 at 18:39

Thanks for the suggestion. I like how dstat has few dependencies, shows trends, and combines all CPUs. I only wish the CPU history were graphical instead of numerical – Andrew Dec 11 '19 at 21:13

nmon is great! It shows historical trends for CPU usage, combines all CPUs into one chart, works on the console, and has light package dependencies. – Andrew Dec 11 '19 at 21:16
