linux - What does a red swap bar mean, in htop?



In htop, there appear bars that show CPU, MEMORY and SWAP.



In What exactly do the colors in htop status bars mean? , I saw the meaning of the colors for the CPU bar and the MEMORY bar.



What do the colors mean in the swap bar?




I could find no mention in the htop man.


Answer



The Swap Bar has only one colour (red) which simply indicates how much swap memory is being used. You can see this by pressing h (or F1) while running htop.
