Time periods

Definition​

Time periods define a time interval for each day of the week. They enable the execution of check commands over a given period of time. Time periods are applied according to the time zone configured on the poller which will execute the check.

Configuration​

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 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.

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 8 AM to noon and from 2 PM to 6:45 PM 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 6 PM to 7:59 AM on weekdays
  • Around the clock on 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 exceptions.

To add an exception, in the Exceptions field, click 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 monitoring: 00:00-00:00.

The table below shows some possible examples:
