I didn’t find a better upgrade method than remove and install yet. Thanks for testing!
I’m working on the module, I hope I can provide an update soon.

Hi Markus, thanks for your work. Great as always!! 
I did a clear install on a test vm and configured a pc with the agent.
Seems to work. Server and PC are communicating.
But I get some Warnings in the systeminformation field:
You configured a config-database “php” in witch I found 2 of this options. But when I change them to the suggested values and expand the template, nothing changes in Zabbix. Even after a reboot.

I am going to provide an update soon with correct php settings and also the database history setting, see Zabbix 5.0 LTS has been released - #20 by dz00te
This is the config db for the default php, not rh-php73.
In the meanwhile you could create following files to get rid of the warnings:
Create /etc/opt/rh/rh-php73/php-fpm.d/zabbix.conf with following content:
php_value[post_max_size] = 16M
php_value[max_execution_time] = 300
php_value[max_input_time] = 300
php_value[date.timezone] = Europe/Vienna
Edit /etc/zabbix/web/zabbix.conf.php and add
$DB['DOUBLE_IEEE754'] = true;
Stop zabbix-server:
systemctl stop zabbix-server
Add patch to db:
cat $(rpm -ql zabbix-server-pgsql | grep double.sql) | sudo -u zabbix psql zabbix
Restart services:
systemctl restart zabbix-server rh-php73-php-fpm

I updated the testing package.
- Included php settings, timezone is set to Nethserver timezone
- Included DB settings
- New images by @Andy_Wismer
- Removed the old zabbix backup script as @syntaxerrormmm provides an RPM for easy deployment
Thanks for testing!
To install:
yum -y install https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
yum -y --enablerepo=zabbix,zabbix-frontend install https://mrmarkuz.dynu.net/mirror/devtest/nethserver-zabbix-0.0.1-8.ns7.noarch.rpm
For updating you need to remove the old zabbix packages and install the new one as described here.
If you already tested you need to reinstall to get the new version:
yum -y --enablerepo=zabbix,zabbix-frontend reinstall https://mrmarkuz.dynu.net/mirror/devtest/nethserver-zabbix-0.0.1-8.ns7.noarch.rpm

I installed Zabbix Agents inside my Nethserver and Proxmox-System.
Both are active (stared and enabled) but inside of the Zabbix host configuration both are not connected.
Do you have a hint or me?
Best regards, Marko

You need to open port 10050 TCP on the machines that have only the agent.
For the nethserver I did:
- Creating new service “zabbix-agent”
- I opend the firewall
- I created a local role
The Zabbix agent isn’t still accessible, but the firewall don’t rejects anymore. Last entry before FW-Konfiguration
Sep 14 17:30:36 nethserver kernel: Shorewall:loc2fw:REJECT:IN=br0 OUT= MAC=xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx SRC=192.168.3.210 DST=192.168.3.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=36828 DF PROTO=TCP SPT=57568 DPT=10050 WINDOW=29200 RES=0x00 SYN URGP=0
For the Proxmox system I have no idea how to open the port. The firewall is inactive.
The zabbix agent is running?
systemctl status zabbix-agent
Please check if zabbix-agent is listening:
netstat -tlpn | grep 10050
# systemctl status zabbix-agent
zabbix-agent.service - Zabbix Agent
Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; enabled; vendor preset: disabled)

# netstat -tlpn | grep 10050

tcp6 0 0 :::10050 :::* LISTEN 9496/zabbix_agentd
Hi Marko
Are both Zabbix Agents correctly configured with correct hostname (Needs to match the zabbix server entry, not necessarily the real hostname!) and IP (On GREEN!)?
I usually put both in double: under Active check and Server (For the server) and under SourceIP and ListenIP (for the Agent itself) in zabbix_agentd.conf…
My 2 cents

Did you setup a firewall rule on the proxmox?
no, I don’t have activated the FW on the Proxmox, Should I do?
I am not enthusiastic about increasing the complexity…
No, it was just an idea. If it’s not active it should be ok too.

oh…
I didn’t configure anything on agent side. I didn’t recognize to have to do so. I thought the installation was sufficient.
Now I have to read the manual 
Best Regards, MArko
IIRC you need to set who can access the zabbix agent in /etc/zabbix/zabbix_agentd.conf and restart the service, I completely forgot about that…
Server=<IP_of_Zabbix_server>

Just set those 4 values and Hostname, maybe define logfile (size).
I also sometimes set these two (mostly on Windows…)
EnableRemoteCommands=1
LogRemoteCommands=1
This is set standard:
Include=/etc/zabbix/zabbix_agentd.d/*.conf
That’s all you need… 
The same for ALL your Linux hosts, also Mac!
I know I’m fast with problem analysis…

Setting a /24 for zabbix server is not a very good idea, nor secure…
If this “EnableRemoteCommands=1” is active, you make things REALLY easy…
Just have the server in there, specifically one or two (If 2 Zabbix servers for redundancy) IPs, comma separated.
Localhost is not needed in the agent-config. If running on NethServer, the only place localhost makes sense is on the server, and your module handles that correctly.
All other host should NOT have localhost in the server field!
My 2 cents

is this a current supported option?
Option: EnableRemoteCommands - Deprecated, use AllowKey=system.run[] or DenyKey=system.run[] instead
Internal alias for AllowKey/DenyKey parameters depending on value:
0 - DenyKey=system.run[*]
1 - AllowKey=system.run[*]
Mandatory: no
