[edit] Zabbix and Vserver guest discovery

Zabbix 2.4+ has an discovery system for ressources like disks and cpu. You can use it to detect running guest and monitor some 'stuff' like this:

• 1/ on the agentd configuration add

UserParameter=vserver.discovery,/pathto/my/script/guestdetect.sh

And restart the agent

• 2/ create the script /pathto/my/script/guestdetect.sh

               #!/bin/bash
               echo -n '{';
               echo -n '"data":['
               I=0;
               for n in $(ls -d /proc/virtual/[0-9]*); do
                       xid=${n##*/};
                       guest=$(vserver-info "$xid" ID);
                       name=$(vserver-info "$guest" NAME);
                       if [ "$I" != "0" ]; then echo -n ','; fi   
                       echo -n "{\"{#GUESTNAME}\":\"$name\",\"{#GUESTCTX}\":\"$xid\"}";
                       I+=1;
                       done
               echo -n "]}";

make it executable : chmod 755 /pathto/my/script/guestdetect.sh;

• 3/ add a discovery rule on a zabbix template using vserver.discovery as the key, then {#GUESTNAME} and {#GUESTCTX} as you see fit in your prototype.

Enjoy !
