What does "LLD" stand for in the context of Zabbix?

In the context of Zabbix, "LLD" stands for Low-Level Discovery. This feature is essential for automating the process of discovering network devices or services dynamically. Low-Level Discovery allows Zabbix to identify and add multiple items, triggers, and graphs from a single configuration. For instance, it can detect things like network interfaces, file systems, or databases automatically, which enhances the efficiency of monitoring by reducing manual configuration efforts.

The term encapsulates the idea that the system is able to discover low-level components of a resource or device, making it easier for administrators to keep their monitoring setup up-to-date without extensive manual input. This functionality is a fundamental part of how Zabbix scales when managing a large number of hosts or various types of resources.
