[Q+A] Monitoring 100 isolated groups

[PizzaProgram]

Hi,

Is it possible to monitor more services running on the same server and see ALL clients together in all those separated groups?
If not, how do I separate groups so I can see all clients as "master group" with this software?

Thank you very much in forward!

More info:

I need to manage 100+ pizzerias.

• Those have each 1-10 windows PC + some iOS/Android phones + some Macs.
• Those groups should never be able to reach each other.
• I need a master group to "see them all".
• No connection is allowed to go to the internet through those groups.
• Some groups should be able to reach some services on the server. (SQL, Mqtt, ... )
• Debian 11, 64 bit, VPS, fix IP, Webmin + "OpenVPN-Administrator v3.3" module installed.
