I needed something to show me load averages of each individual VE quickly.

Figured I would share it with the community in case someone else was
looking for similar functionality.

however I don't really care since its under 50 lines anyway :)

Also, as a side note, I'm really really good at reading man pages.

(What I really mean is I'm not)

Thanks guys!

PS: Mine has color :P

Some fixes to work better :

case $OPTION in
h)
echo "usage $0 options"
echo "OPTIONS:"

echo " -H Disable the header"
echo " -C Disable colors"
exit 1
;;
H)
NO_HEADER=1
;;
C)
NO_COLOR=1
;;
esac
done

if [ $NO_HEADER -eq 0 ]; then
printf " %-15s %-20s %-15s %-9s %s\r\n" "VEID" "Hostname"
"Load: 1min" "5min" "15min"
fi
for VEID in `vzlist -H -octid`; do
source /etc/vz/conf/$VEID.conf
#LOADTOTAL=$(cat /vz/root/$VEID/proc/loadavg | awk '{print
$1,$2,$3}')
LOADTOTAL=$(vzctl exec 312 cat /proc/loadavg | awk '{print
$1,$2,$3}')
LOAD_1MIN=$(echo $LOADTOTAL | awk '{print $1}')
LOAD_5MIN=$(echo $LOADTOTAL | awk '{print $2}')
LOAD_15MIN=$(echo $LOADTOTAL | awk '{print $3}')
LOAD=${LOAD_1MIN/.*}
[ ${#HOSTNAME} -gt 20 ] && HOSTNAME="${HOSTNAME:0:17}..."
if [ $NO_COLOR -eq 0 ]; then
[ $LOAD -lt 3 ] && COLOR="\033[1;32m"
[ $LOAD -ge 3 ] && COLOR="\033[1;33m"
[ $LOAD -ge 7 ] && COLOR="\033[1;31m"

And so we'll see the load avg for VEID 312 as many times as your VPS count is. Replace please 312 with $VEID.
