What type of data can be monitored with pre-defined templates in Zabbix?

The answer accurately reflects the capabilities of Zabbix regarding pre-defined templates. In Zabbix, pre-defined templates are designed to facilitate the monitoring of a wide range of different system and network metrics. These templates include configurations for monitoring various parameters such as CPU load, memory usage, disk space, network traffic, and more across different systems and devices.

Using these templates allows administrators to quickly deploy monitoring without needing to create each item or configuration from scratch. The flexibility and comprehensive coverage of metrics provided by these templates enable effective monitoring of both infrastructure and the applications running on it. This is useful for maintaining system performance, ensuring uptime, and proactively identifying potential issues.

In contrast, the other options suggest a limited scope. Focusing only on application errors, general server settings, or database performance would restrict the monitoring capabilities, whereas Zabbix's pre-defined templates are integrated to provide a holistic view of the monitored environment.
