What is the primary purpose of host groups in Zabbix?

The primary purpose of host groups in Zabbix is to provide a logical grouping of hosts and templates. This organizational feature allows users to manage multiple hosts efficiently by categorizing them based on various criteria such as function, location, or type of service.

By using host groups, administrators can apply templates, which contain predefined monitoring checks and parameters, to multiple hosts simultaneously rather than configuring each host individually. This not only simplifies the monitoring process but also ensures consistency in monitoring configurations across similar hosts. The logical structure offered by host groups makes it easier to manage permissions and visibility, allowing users to focus on specific subsets of hosts relevant to their responsibilities or organizational needs.

In contrast, monitoring network traffic, tracking user access rights, and creating dashboards are important features of Zabbix but do not embody the central role that host groups play in organizing and managing hosts and templates effectively.
