I made another version which can handle per VE graphs and labelling. This is good for me, because I can present this graphs to my subscribers.

<pre>
#!/bin/sh
#
# plugin to monitor OpenVZ bean counters.
#
#
#%# family=auto
#%# capabilities=autoconf suggest

VEID=$(basename $0 | sed -e 's/^vz_//g' -e 's/_.*$//g')
NAME="$VEID: "$(basename $0 | sed -e 's/^vz_[0-9]\+_//' -e 's/_.*//' -e 's/-/ /g')
ATTRS=$(basename $0 | sed -e 's/^vz_[0-9]\+_[^_]\+_//g' -e 's/_/|/g')

if [ "$1" == "autoconf" ]
then
if [ -r /proc/bc/0/resources ]
then
echo yes
exit 0
else
echo "no (/proc/bc/0/resources not found)"
exit 1
fi
fi

if [ "$1" == "suggest" ]
then

if [ -r /proc/bc/$VEID/resources ]
then
cat /proc/bc/$VEID/resources |
while read str
do
vals=($str)
echo ${vals[0]}
done

exit 0
else
exit 1
fi
fi

if [ "$1" == "config" ]
then

# echo "graph_order down up"
echo "graph_title $NAME"
echo 'graph_category OpenVZ'
echo "graph_info '$NAME'"

grep -E $ATTRS /proc/bc/$VEID/resources |
while read str
do
vals=($str)
name=${vals[0]}
echo ${name}.label $name
echo "${name}.warning ${vals[3]}"
echo "${name}.critical ${vals[4]}"
done

exit 0
fi

grep -E "$ATTRS" /proc/bc/$VEID/resources | while read str
do
vals=($str)
name=${vals[0]}
echo "${name}.value ${vals[1]}"
done
</pre>
Then I can made links to the /etc/munin/plugins in this way:
<pre>
vz_1013_Filesystem-informations_numfile_numflock -> /root/munin/vz
vz_1013_Memory_privvmpages -> /root/munin/vz
vz_1013_Network-buffers_tcpsndbuf_tcprcvbuf_dgramrcvbuf_othersockbuf -> /root/munin/vz
vz_1013_Number-of-processes_numproc -> /root/munin/vz
vz_1013_Number-of-sockets_numtcpsock_numothersock -> /root/munin/vz
</pre>
It's not better or worster than the original. It has just different purpose. Maybe this can be put on the front page as an option.
