Which entities can be tagged in Zabbix?

In Zabbix, tagging provides a way to categorize and organize various entities within the monitoring system, allowing for more streamlined management and visibility. The entities that can be tagged include hosts, templates, triggers, items, and macros.

Each of these entities serves a specific role within Zabbix, and tagging them helps to create a better overview and filtering capability, especially in complex environments. For instance, tagging templates can help in identifying which templates are used across various hosts, while tagging triggers can assist in monitoring specific issues based on their categorization, such as performance problems or service failures.

By allowing tags on all these entities, Zabbix enables administrators and users to easily group and filter monitored elements based on the tags assigned, making it simpler to analyze data and respond to alerts. This comprehensive capability is essential for effective monitoring and management within Zabbix, which is why the correct answer encompasses all mentioned entities.
