What is one function of the Config Cache in Zabbix Server?

The Config Cache in Zabbix Server plays a critical role in enhancing performance and efficiency by holding configuration settings. It is designed to store information about the configuration of various Zabbix entities, such as hosts, items, triggers, and other related settings. By keeping this data in memory, the Config Cache allows for rapid access and reduces the need to repeatedly read configuration files or the database, which can be time-consuming and resource-intensive.

When Zabbix processes requests, it doesn't always need to query the database for each item it needs; instead, it can retrieve this information directly from the cache. This significantly speeds up operations such as checks and monitoring tasks, ultimately improving the overall responsiveness of the Zabbix Server.

In contrast, functions like storing user data, managing log files, or interfacing with external APIs are handled by different components or mechanisms within Zabbix and do not fall under the purview of the Config Cache. This distinct role of holding configuration settings is what sets the Config Cache apart in the Zabbix architecture.
