Defining a time frame for blackout policies

 Create a time frame to specify the time period for the blackout policy to be active.

Best Practice

  • Do not create a time frame that a blackout policy might never use. For example, a time frame that covers a complete day, that is "24x7", will never be used because a blackout policy will not be applied all the time.
  • Do not create overlapping time frames to avoid confusion.
  • Include an abbreviation for the time frame in its name. For example, a time frame that starts at midnight on Friday and ends at midnight on Sunday can be named “Weekends.” If a time frame is related to a specific maintenance period for a specific application, include an abbreviation of the application name in the name as well as a representation of the actual time period for the time frame.
  • Provide a description for each time frame and specify the information with maximum impact at the beginning of the description. For example, 31 Oct - Windows upgrade.

Time frame properties

PropertyDescription
NameName of the time frame
DescriptionA brief description about the time frame
Start TimeStart time for the time frame. The value must be in the 24-hour format. For example, 10:55; 13:30.
End Time/Duration

End time or duration for the time frame. You have the following options:

  • Time: Actual end time. The value must be in the 24-hour format. For example, 15:30
  • Duration: Duration of the time frame from the start time. You can specify the duration in hh (hours):mm (minutes) format. For example, if the start time is 10:55 and the selected duration is 01:15, the calculated end time is 12:10.

Important: Time frames based on start and end times cannot span across midnight. Hence, in this case, you must specify the duration. For example, if you want a weekly time frame that starts at 6:00 P.M. on Saturday night and ends at 6:00 A.M. Sunday morning, create a time frame with the following properties:

Recurrence Pattern: Weekly (Saturday)

Start Time:18:00

Duration: 12:00

Recurrence Pattern

Occurrence frequency of the time frame. The supported patterns are as follows:

  • Always active: Indicates that the time frame is always active. You have the option to activate the time frame immediately or you can set the date from when you want the time frame to be active.
  • Once: Indicates that the time frame gets activated on the selected date. Specify the date for the time frame to be active.
  • Daily: Indicates that the time frame gets activated every day. You have the option to activate the time frame every day or only weekdays (Monday through Friday). This is the default option.
  • Weekly: Indicates that the time frame gets activated on the selected days of the week.
  • Monthly: Indicates that the time frame gets activated on the selected days of a month. You can provide a single day, multiple days, or a range of days. For example, 10, 10-15, or 5,10,15.
