I have a Zabbix server currently setup for my company. I've been asked to configure it for 4 or 5 other sister company's. Is there a way within Zabbix to create multiple sites or separate what servers specific user accounts can view, configure, interact with etc? Basically I need to come up with a way to only allow each sister company to see and receive notifications of their own servers and NOT anyone else's. I unfortunately could not find anything specific to this in my search in this forum.
