Is there any Widget that can show my CPU and other performances live?

I am ubuntu user currently working on Image Processing Project, I need to have a constant look at my CPU and Ram usage which is shown in system monitor very clearly but I have to switch between system monitor and my Project to see the graphs and cpu usage. Is there any solution so that I don't have to switch and there is widget at the status bar that can show these performances other than small Icons like indicators.

Solution 1:

Conky

Conky is a popular light weight system monitor. I have it running on the right side of one of my monitors all the time:

The GIF animation show 2 dozen seconds with youtube running and then closed. Then you'll notice a single core getting most of the activity for the screen recorder itself.

This is the conky code I used (minus the header section which can be desktop specific):

Solution 2:

For the ultimate convenience I've found this gnome extension, install it's dependencies first, then hit the switch on the web page.

sudo apt-get install gir1.2-gtop-2.0 gir1.2-networkmanager-1.0  gir1.2-clutter-1.0

I've realized you already mentioned system monitor now so i'll move these two to the bottom...

Ubuntu has System Monitor built into it, simply search for that in the applications menu.

HTOP is a popular commandline alternative for that pro hacker feel. Install it with sudo apt install htop
