How often do changes made in the Zabbix frontend show up in the database by default?

The frequency with which changes made in the Zabbix frontend are reflected in the database by default is once per minute. This timing is set to balance the need for consistency in monitoring configuration with the performance considerations of the database. By updating the database on a one-minute interval, the system ensures that changes are not recorded too frequently, which could lead to unnecessary load on the database, while still providing a reasonable level of responsiveness for users making adjustments to items, triggers, and other configurations.

This timing allows the system to handle multiple changes efficiently, consolidating them and providing a smoother performance overall. Hence, changes are not immediately written to the database in real-time, which helps to optimize resource use and avoid potential performance degradation that could occur if the updates were processed too frequently, such as every second.
