Multiple maintenance periods
Depending On the resource for which you are configuring the maintenance period, you can create a single or multiple maintenance periods. When a resource has multiple maintenance periods defined, following rules apply:
- If maintenance period windows do not overlap, they are treated as two independent maintenance windows.
- If the maintenance windows overlap, they are treated as single window encompassing the time period covered by both maintenance windows. For example, if two windows each an hour in duration overlap by 30 minutes, the effective duration of the maintenance window would be 90 minutes.
Prerequisite for overlapping scheduled maintenance
You must have Device Manage permission to create maintenance periods on a resource.
To get alert notifications, you must configure alert notifications in My Profile section.
Alert Conditions and its behavior during the overlapping period
Alert conditions help you to define the criteria for Maintenance alerts. If you want specific alerts to be triggered as Maintenance alerts, configure the Alert Conditions. During overlapping maintenance period, alert conditions defined in both maintenance windows are considered. However, after the overlapping maintenance period ends, the alert conditions defined in the second window would be be considered.
