I have a 48-CPU UBUNTU and it has loaded with lots of processes. Here is the htop page, enter image description here

At core section, the green bar means the usage from normal user, the red one represents the kernel usage, but what is the 3rd color stands for ? Thanks.

Here is what I have seen on the same terminal when I click F1 button. enter image description here

htop has multiple color schemes that get defined in ~/.config/htop/htoprc which is inherited from /etc/htoprc However it is not recommended to edit these files manually as the configuration can be changed via the in-program setup configuration (press F2 in the program to access this).

You can see what your current color scheme is by pressing F1 inside the program.

The default color scheme is:

  • Dark Blue – Indicates CPU percentage used by low priority processes. Low processes in htop are indicated by an exit value of greater than 0.
  • Green – shows processes running as regular users in the system.
  • Red – shows kernel threads.
  • Aqua Blue – shows virtualized processes.

  • I've never touched that "~/.config/htop/htoprc" file, so it should be whatever the original settings are. And when I press "F1" on htop, I do see the message about which cloud matches with what type of process, and it displays exactly like the one on this page, https://www.cloudsavvyit.com/7847/color-bars-in-htop-what-do-they-mean/, and that is why I am confused for the 3rd bar color on my htop page. – user3595231 Apr 08 '22 at 19:14
  • I agree. but the color I listed does not match any of these. – user3595231 Apr 08 '22 at 20:03
  • I have just updated my original post when F1 button is clicked on the same terminal. – user3595231 Apr 08 '22 at 20:27
  • @user3595231: strange, not sure what your issue is but I'll leave my answer up incase someone else with a similar issue stumbles on this. – jesse_b Apr 08 '22 at 21:04
  • Could you please elaborate on "excellent value"? – asgs Jan 01 '23 at 20:39

    @asgs sorry I'm sure I meant exit – jesse_b Jan 02 '23 at 21:47
  • ah, that makes sense :-) thank you! – asgs Jan 03 '23 at 14:48
  • I can't understand "exit value". Shouldn't that be "nice value"? – iBug Apr 19 '23 at 18:47
