Alarm Maintenance Windows

The Maintenance Window feature in the Alarm module defines a scheduled time period during which monitoring alerts are temporarily suppressed, muted, or deprioritized while planned work is performed on a system.

Purpose

• It prevents false or expected alerts during deployments, patches, upgrades, or infrastructure changes.
• This avoids unnecessary escalations or incident tickets.
• It also keeps monitoring reports clean and meaningful.

The overview page displays all created maintenance windows with these details:

• Name: Name of the maintenance window.

• Alarm rule targeted: Alarm rule to which the maintenance window applies.
• Matching label: Labels assigned to the maintenance window.
