When you create a maintenance schedule, you name it and provide a description.
The default duration for maintenance schedules is one hour and the default start time is immediately. Since maintenance schedules cannot be edited while running, if you want to change the default start time, date, or duration, change those options before you click the Save button.
When you create a schedule, you mark it as Planned or Unplanned. If you select Planned, the downtime of the affected devices, sites, and network services does not appear as downtime on reports.
If maintenance schedules overlap and one of them has the status of Planned, while the other is Unplanned, the overlapping time is set as Unplanned and the downtime of the affected devices, sites, and network services appears as downtime on reports.
The minimum duration is .5 hour. In the Duration box, any fraction of an hour less than .5 hour is rounded up to .5 hour. Over .5 hour, numbers are rounded to one decimal place.
