Alternative to vzprocps
As far as I know the OpenVZ associated vzprocps-tools are just available in version 2.0.11, at least for Debian. Unfortunately they are damn buggy in this version, so unusable…
There are two smart tools included in vzprocps : vztop and vzps . These programs help you a lot dealing with processes of your running containers. But in 2.0.11 they aren’t working:
root@serv: ~ $ vzps
Segmentation fault
root@serv: ~ $ vztop

Segmentation fault
root@serv: ~ $It seems that there is an update, but not available as .deb yet. Here is an example for an alternative to vzps to find zombies:
CONTAINER=$(/usr/sbin/vzlist | /bin/grep running | /usr/bin/awk '{print $5}')
for ct in $CONTAINER;
do
echo "processing: $ct";
/usr/sbin/vzctl exec $ct '/bin/ps -ef | /bin/grep defunct';
doneIt’s a bit complicated, but you can write a small script to grep for further things..
