Why is it important to suppress alerts during maintenance in Zabbix?

Suppressing alerts during maintenance in Zabbix is important primarily to reduce unnecessary disruptions for system administrators. When maintenance activities are being performed, such as updates or repairs, it is common for certain services to be intentionally down or performing erratically. If alerts were still generated during these periods, it could overwhelm administrators with notifications about issues they are already aware of, leading to confusion, frustration, and potential oversight of real issues that may arise once the maintenance is complete.

By silencing those alerts, Zabbix helps ensure that system administrators can focus on the maintenance tasks at hand without being distracted by alerts that would not provide meaningful insights during that time. This streamlined approach enhances the efficiency of the maintenance process, as it minimizes interruptions and ensures that the team can concentrate on resolving any existing maintenance-related concerns.

While visibility of maintenance activities to all users can be beneficial, it does not directly pertain to the goal of reducing unnecessary alerts. Similarly, generating more alerts during downtime and maintaining consistent monitoring coverage are counterproductive to the purpose of suppressing alerts during maintenance, which is focused on clarity and efficiency for the administrators involved.
