text: On the Schedules tab, you can define or change schedules for the user account. You can use schedules to pause monitoring and notifications for certain time periods with the period lists option. Also, you can activate monitoring and notifications at certain times with the time table option. You can also use schedules to define the time periods that PRTG covers when you create reports.
  This documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.
  If 15 minutes (900) seconds have passed since your last credential-based login and you open a setup page from a different setup page, PRTG asks you to enter your credentials again for security reasons. A dialog box appears. Enter your Login Name and Password and click OK to continue.

  Schedules Settings
  When a user with administrative rights creates a new object, only other users with administrative rights can view or edit the new object by default. When a read/write user creates a new object, all members of the read/write user's primary group can view and edit the new object as well. This behavior applies to libraries, maps, reports, notification templates, and schedules. For more information, see section Access Rights Management.
  Click the Schedules tab to show a list of all schedules. To edit a schedule, enable the check box next to a schedule and choose from the following options:
  Option
  Description
  Used by ( )

  Basic Settings
  Edit Schedule Time Table
  Setting
  Description
  Schedule Name
  Enter a meaningful name for the schedule.
  If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?
  Tags
  Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.
  For performance reasons, it can take some minutes until you can filter for new tags that you added.
  For more information, see section Tags.
  Selection Method
  Select the method that you want to use to define a schedule:
  Use weekday/hour time table: Select specific days of the week or specific hours in which the schedule is active. This means that monitoring objects, notifications, and reports are not paused.
  Use list of period definitions: Enter a list of period definitions in which the schedule is inactive. This means that monitoring objects, notifications, and reports are paused.
  Time Table (active time slots)
  This setting is only visible if you select Use weekday/hour time table above. Enable or disable check boxes or use buttons to define the schedule. You have the following options:
  Weekday buttons ( ): Use the weekday buttons Mo, Tu, We, Th, Fr, Sa, and Su to define the days of the week in which the schedule is active. For example, click the Mo button to set the schedule to active for all hours every Monday. This enables all check boxes under the Mo column.
  Hour buttons ( ): Use the hour buttons 0:00 - 23:00 to define the hours of the day in which the schedule is active. For example, if the 0:00 button is blue, click it to set the schedule to active for the hour 0:00 of all days of the week. If the 0:00 button is white, click it to set the schedule to inactive for the hour 0:00 of all days of the week.
  All off button ( ): Use the All off button to disable all check boxes, and to deselect all weekday buttons and hour buttons.
  All on button ( ): Use the All on button to enable all check boxes, and to select all weekday buttons and hour buttons.
  For more information, see also Schedules and Time Zones below.
  Period List (inactive time slots)
  This setting is only visible if you select Use list of period definitions above. Enter the date and time periods in which the schedule is inactive. The periods must have the following format:
  ww:hh:mm-ww:hh:mm
  Make sure that you enter each period exactly in this format. Otherwise you receive an error message. Go back to the schedule and correct the period in this case. For details and examples, see Period Definition Syntax below.
  For more information, see also Schedules and Time Zones below.
  Access Rights
  Setting
  Description
  User Group Access
  Define the user groups that have access to the object. You see a table with user groups and group access rights. The table contains all user groups in your setup. For each user group, you can choose from the following group access rights:
  No access: Users in this user group cannot see or edit the object. The object does not show up in lists.
  Read access: Users in this user group can see the object and view its settings.
  Write access: Users in this user group can see the object and view and edit its settings. However, they cannot edit the object's access rights settings.
  Full access: Users in this user group can see the object, view and edit its settings, and edit its access rights settings.
  You can create new user groups in the User Groups settings.
  Click OK to save your settings. If you close the dialog without saving, all changes to the settings are lost.
  Schedules and Time Zones
  Schedules use the time zone of the PRTG core server system. This might be different from other time displays in PRTG that are saved in UTC.
  If you select Use weekday/hour time table, PRTG converts the time in which the schedule is active to the time zone of the user account. This means that the schedule applies according to the time that the user account shows.
  If you select Use list of period definitions, PRTG does not adjust the time in which the schedule is inactive to the time zone of the user account. The schedule applies according to the time on the PRTG core server system in this case. Because of this, you encounter time shifts for schedules if there are changes to the time zone on the server or because of daylight saving and standard time changes.
  Period Definition Syntax
  Define one or more periods of time during which the object that uses this schedule is inactive. In each line, enter one range in the format ww:hh:mm-ww:hh:mm. The following values are possible:
  ww: mo, tu, we, th, fr, sa, su.
  hh: Enter the hour in the 24-hour format. For example, a number between 00 and 23.
  You must use the 24-hour format. You cannot use A.M./P.M.
  mm: Enter the minute. For example, a number between 00 and 59.
  Example
  This example shows a schedule that pauses an object during the weekend as well as on Wednesday evenings.
  fr:19:30-mo:06:05
  we:18:45-we:23:00
  Any object that uses this schedule is inactive (paused) from Friday, 7:30 P.M. to Monday, 6:05 A.M. as well as on Wednesday from 6:45 P.M. to 11 P.M. It is active during the other times.
