PRTG Manual: Scheduling
With the help of schedules you can pause the monitoring of certain objects automatically for a certain time, for example, on Sundays between 4 and 8 a.m. A paused sensor will not collect monitoring data, will not change its status, and will not trigger any notifications. You can also pause monitoring for planned system maintenance time spans to avoid false alarms. You can apply different schedules to every object. Schedules are also used for reports and notifications.
If you pause a master object by schedule or manually, you do not trigger a status change by dependency. See also this Knowledge Base article Why will dependent objects not go into paused status automatically when I pause the master object?
Available Default Schedules in Device Settings
Schedules are user account specific. To change the default pre-defined schedules or to add your own schedule, see Account Settings—Schedules section.
If you use failover clustering with nodes in different timezones, scheduling applies at the local time of each node. For more information, see section Failover Cluster Configuration—Before Getting Started.
