nmon on your headless Proxmox server

Proxmox is great and after it is up and running you can control it from the web page or ssh in, so what do you do with the monitor connected to it. Here is a one-line command to get nmon to show you what the server is doing.

I set my script up in cron so it always comes up, also nmon will not refresh the entire screen so cron can also kill the old nmon and start a new one.

I called this headless because you don't need to login to have this work. The pgrep command finds the getty that has the login prompt.

( sleep 2; 
export NMON=cmVdn; 
export TERM=xterm-color; 
export NCURSES_NO_UTF8_ACS=1; 
nmon > /proc/$(pgrep -f agetty)/fd/1 ) &

And this is what it looks like.
