Which feature allows for automated resource monitoring in Zabbix?

Low-Level Discovery (LLD) is the feature in Zabbix that enables automated resource monitoring. It functions by automatically discovering items, triggers, and graphs based on predefined rules. This means that if new resources are added to the monitored environment—such as new file systems, network interfaces, or processes—LLD can detect these changes and create the necessary monitoring items without manual intervention from the administrator.

This capability significantly reduces the operational overhead associated with manually configuring new resources for monitoring, thereby enhancing the efficiency and scalability of the monitoring setup. By using LLD, Zabbix can adapt to changes in the IT environment in real-time, ensuring that all relevant metrics and alerts are promptly incorporated into the monitoring framework.

Other choices, such as event triggers, are important for defining when alerts should be generated based on certain conditions or metrics, while user access settings control permissions for individuals interacting with the Zabbix interface. Notification mediums relate to how alerts are communicated to users but do not contribute to the monitoring setup itself. Only Low-Level Discovery specifically facilitates the automation of resource monitoring.
