There had been updates in the ticket and also a conversation in Slack.

Jiri Novak will create a user group "o3" in zabbix. I added a DHCP and hosts entry for a zabbix proxy host within the o3 DMZ.

To add more hosts to monitoring we can execute the following:

zypper ref
zypper in -y zabbix-agent

(Jiri Novak) so ariel has the data in zabbix properly now. if you want to add any more hosts like this, you can run the bunch of commands and it will auto-add to zabbix. i'll make you users into web interface in the evening
