Where can global notifications be configured in Zabbix?

In Zabbix, global notifications can be configured within the user profile under the messaging settings. This area provides options for customizing how users receive alerts and notifications, such as email, SMS, or through the Zabbix frontend. Users can set their preferences for receiving notifications effectively, ensuring that they are informed about relevant system events.

The specified choice is correct because global notifications directly relate to user-specific settings that allow for customization of notification channels, which are crucial for operational awareness in monitoring environments. By configuring these settings within the user profile, Zabbix provides flexibility and personalization in how users are alerted to issues.

The other options focus on different settings or configurations that do not directly pertain to global notification configurations. Thus, they don't provide the necessary context or functionality to adjust global notification settings effectively.
