How do you prevent false alerts during a known-busy period using a work mode?

A work mode sets a start/end window for a managed object and changes its alert/metric config during that window.

Uses: raise thresholds for a known-busy period to stop false alarms, change notification settings (e.g. an offshore team only notified during go-live), or define a maintenance window that disables monitoring. Created and scheduled in the event-planning IT calendar.
