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.
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
}
