Time periods


Time periods define a time interval for each day of the week. They enable the functionalities of the scheduler over a given period of time. They apply to two types of actions:

  • The execution of check commands
  • The sending of notifications.


To configure a time period, go to Configuration > Users > Time periods.

  1. In the Time Period Name and Alias fields, enter a name and a description.

  2. In the Basic settings section, for each day of the week, define the time periods during which the checks and notifications will be enabled. (Use the syntax described below.)

    • These definitions are applied every week, indefinitely.
    • If you leave the field blank for a specific day, there will be no monitoring on that day for actions to which this time period is applied.
  3. Use the Time Range Exceptions tab to include days that would not normally belong to the time period.

  4. Once you have created your time period, you can use it:

    • In the Check Period field for hosts, host templates, services and service templates.
    • In the Notification Period field for notifications defined for hosts, host templates, services, service templates, contacts, or in the Escalation Period field for an escalation of notifications.

Syntax of a time period

Use the following characters to define time periods:

  • The character “:” separates the hours from the minutes. E.g.: HH:MM
  • The character “-” indicates continuity between two time periods
  • The character ”,” separates two time periods

Here are a few examples:

  • 24 hours a day and 7 days a week: 00:00-24:00 (to be applied to every day of the week).
  • From 08h00 to 12h00 and from 14h00 to 18h45 on weekdays: 08:00-12:00,14:00-18:45 (to be applied to weekdays only).


Time Range Exceptions tab

The Time Range Exceptions tab allows you to include exceptional days in the time period. The periods you define here override the definition of regular days defined in Basic Settings.

Example: An administrator wants to define a time period which covers the times when the offices are closed, i.e.:

  • From 18h00 to 07h59 on weekdays
  • Round the clock at weekends
  • National holidays and exceptional closure days.

To be able to define the national holiday days and the exceptional closure days, it is necessary to use the exceptions.

To add an exception, in the Exceptions field, click on Add new entry. For each exceptional day, you will need to define a time period.

Use the following syntax to exclude whole days from the supervision: 00:00-00:00.

The table below shows some possible examples :

june 1200:00-08:00,18:00-24:00Supervise every June 12th, except between 08h00 and 18h00
