When installing the Zabbix agent on a new host, the Hostname parameter in zabbix_agent2.conf is automatically populated, standard with just Hostname. In modern environments especially cloud-based, containerized, or dynamically provisioned systems it's common for the system hostname to be generic or non-unique. This requires intervention through additional script or manual zabbix_agent2.conf modifications to ensure proper host identification in Zabbix.

Introduce a mechanism during agent installation or configuration that automatically sets the Hostname parameter to the system's Fully Qualified Domain Name (FQDN).
