Nagios Core - Time Period Inheritance

Overview

This article describes how time period inheritance works in Nagios Core.

The name directive must be defined in the parent object for inheritance to work.

The parent object is being referenced by the use directive.

The name directive is not mandatory and hence it can be mistaken with the timeperiod_name directive.

Examples

Here is an example of a config that WILL NOT inherit the parent object 24x7 because the name directive does NOT exist.

define timeperiod {
    timeperiod_name 24x7
    alias 24 Hours A Day, 7 Days A Week
    sunday 00:00-24:00
    monday 00:00-24:00
    tuesday 00:00-24:00
    wednesday 00:00-24:00
    thursday 00:00-24:00
    friday 00:00-24:00
    saturday 00:00-24:00
    }

define timeperiod {
    timeperiod_name maintenance-periods
    alias Maintenance Periods
    sunday 01:00-02:00
    saturday 01:00-02:00
    }

define timeperiod {
    timeperiod_name 24x7-except-maintenance-periods
    alias 24x7 Except Maintenance Periods
    use 24x7
    exclude maintenance-periods
    }

Here is an example of a config that will inherit the parent object 24x7 because the name directive exists.

define timeperiod {
    timeperiod_name 24x7
    name 24x7
    alias 24 Hours A Day, 7 Days A Week
    sunday 00:00-24:00
    monday 00:00-24:00
    tuesday 00:00-24:00
    wednesday 00:00-24:00
    thursday 00:00-24:00
    friday 00:00-24:00
    saturday 00:00-24:00
    }

define timeperiod {
    timeperiod_name maintenance-periods
    alias Maintenance Periods
    sunday 01:00-02:00
    saturday 01:00-02:00
    }

define timeperiod {
    timeperiod_name 24x7-except-maintenance-periods
    alias 24x7 Except Maintenance Periods
    use 24x7
    exclude maintenance-periods
    }
