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:
1 2 3 4 5 6 7 8 9 10 11 | 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 CPU0 states: 0.1% user 0.1% system 0.0% nice 0.0% iowait 98.0% idle 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:
1 2 3 4 5 6 | 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'; done |
It’s a bit complicated, but you can write a small script to grep for further things..
