Show only graph in htop output

htop is unaware it is running on a kernel level virtualized environment (Dreamhost VPS is using VServer technology). It is then showing the CPU usage for all the OS instances sharing the same kernel, not just yours.

Have a look to vtop output which sho ws all processes sharing the CPUs, not just the ones in your container.

If vtop is not installed, and this is probably expected for a commercial solution as one wouldn't like to a customer to see what processes are running other customers, there is no way to fix the issue from inside your container, unless patching top source to compute CPU usage instead of getting it from the kernel statistics.

It might do it by summing up CPU usage of all the processes running in your VServer, e.g.:

ps aux | awk '
    {cpu+=$3; ram+=$6} 
    END {printf("cpu: %d%%, RAM: %.2f MiB\n",cpu,ram/1024) }'

Don't you have colors?

    Green        Blue             Orange
Mem[|||||||||||||||||||||||||||||||||||||||||||| 1978/7847MB]

Where green should be 1978 MiB.

Else you can enter F2 -> Under setup stay on "Meters" -> Right arrow to get to "Left column". -> Down 1 to get to "Memory Bar".

Then press enter to view various ways of display.

When it comes to what the bar displays it is like this.

It reads /proc/meminfo and show - colors depend on "Colors" setting - this is default:

Used U (green): (MemTotal - MemFree) - (Buffers + Cached) / 1024

And then the percentage of MemTotal of that.

Bar:

 Green               Blue                 Orange/Yellow
[Used U % of total | Buffers % of total | Cached % of total ] Used U / Toatal MB

I have a script some where that makes it as well. Have to look for it.
