Linux – htop, show cpu side by side

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) }'

You can pretty much configure it at your will pressing S inside htop.

However, I also did not find anything to erase all the processes. But, you can call it to see only the processes as one user. So you can call it as:

$htop -u nobody

Which is actually the closest I managed to do it.

Press S.

First in "Setup", you go to "Columns", and delete all except "Command" that cannot be deleted. Finally you press F10 to leave.

If you do not wish for the changes to be permanent, run the following command before the manual steps described.

$chmod a-w ~/.config
