Which file contains the main configuration settings for the Zabbix server?

The main configuration settings for the Zabbix server are found in the zabbix_server.conf file. This configuration file is essential for defining various parameters that help the Zabbix server operate correctly. These parameters include settings related to database connections, timeout values, and specific operational aspects of the server itself, enabling effective monitoring and management of networked systems.

The other options represent configuration files for different components of the Zabbix ecosystem. The zabbix_agent.conf is used for the Zabbix agent, which collects and sends data to the server. The zabbix_proxy.conf is related to the Zabbix proxy, an intermediary that gathers data from agents and forwards it to the server, typically used to manage distributed networks. Lastly, zabbix_frontend.conf is associated with the web frontend of Zabbix, which handles user interactions and presentation but does not dictate the operational parameters of the server itself. Thus, the correct file for main server configurations is indeed zabbix_server.conf.
