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
 00:29:11  up 1 day,  5:18,  3 users,  load average: 1.14, 1.26, 1.23
1949 processes: 1946 sleeping, 2 running, 1 zombie, 0 stopped

CPU1 states:   4.1% user  15.0% system    0.0% nice   0.0% iowait  80.0% idle
CPU2 states:   2.0% user   3.0% system    0.0% nice   0.0% iowait  94.0% idle
CPU3 states:  14.0% user  20.1% system    0.0% nice   0.0% iowait  64.1% idle
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;
	echo "processing: $ct";
	/usr/sbin/vzctl exec $ct '/bin/ps -ef | /bin/grep defunct';

It’s a bit complicated, but you can write a small script to grep for further things..
