Talk:Monitoring openvz resources using munin

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.

#!/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

Then I can made links to the /etc/munin/plugins in this way:

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

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. —The preceding unsigned comment was added by Arpad (talkcontribs) 16:06, 29 June 2007.
