Time periods


A time period is the definition of a time interval for each day of the week. These time periods enable the functionalities of the scheduler over a given period of time.

Time periods apply to two types of actions:

  • Execution of check commands

  • Sending of notifications


The configuration of time periods is done in the menu: Configuration > Users > Time periods.

Basic options

  • The Time period name and Alias fields define the name and description of the time period respectively.

  • The fields belonging to the Time range sub-category define the days of the week for which it is necessary to define time periods.

  • The Exceptions table enables us to include days excluded from the time period.

Syntax of a time period

When creating a time period, the following characters serve to define the time periods :

  • The character “:” separates the hours from the minutes. E.g.: HH:MM

  • The character “-” indicates continuity between two time periods

  • The character ”,” serves to separate two time periods

Here are a few examples:

  • 24 hours a day and 7 days a week: 00:00-24:00 (to be applied on 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 on weekdays only).


Time Range exceptions

The exceptions allow us to include exceptional days in the time period (overload of the definition of regular functioning of the day).

E.g.: 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 holidays days and the exceptional closure days, it is necessary to use the exceptions. To add an exception, click on the button navigate_plus. For each exceptional day, you will need to define a time period. The table below shows some possible examples :
