Can a trigger belong to multiple hosts in Zabbix?

A trigger in Zabbix can indeed belong to multiple hosts, and this is fundamental to how Zabbix operates in a more efficient manner. This capability allows for reusability of triggers across numerous hosts, which is particularly advantageous when you manage a large number of similar hosts that require the same conditions for alerting.

When a trigger is created, it can be associated with a specific host directly or through a template. Associating a trigger with a template means that any host linked to that template will automatically inherit the trigger, thereby spanning multiple hosts without the need to configure each one individually. This approach streamlines management and configuration processes.

The flexibility offered here enables Zabbix users to create complex monitoring rules and relationships that are consistent across multiple hosts, ultimately improving the oversight and responsiveness of IT systems. It's important to note that the relationships and logic defined in triggers are designed to be versatile, catering to diverse requirements across various hosts.
