Linux – Possible to override contacts for just one Nagios host group

centoslinuxnagiosUbuntu

The contact for all my linux hosts is the admins Nagios contact_group. But for this one Linux host would I like that the contact_group called sandradebug also gets notified.

The problem is, that when I add contact_groups sandradebug it is still only admins that gets the notification and not also sandradebug.

Question

How can I include sandradebug for this one host, so notifications are also sent there?

Host template

define host {
  name                          linux-host
  use                           generic-host
  check_command                 check-host-alive
  notification_interval         4320
  notification_options          d,u,r
  contact_groups                admins
  register                      0
}

Host definition

define host {
  use                     linux-host
  host_name               example
  alias                   example
  address                 10.10.10.10
  hostgroups              default-linux-services
  contact_groups          sandradebug
}

Have you restarted the Nagios? Your above configuration will override the template values and only sandradebug group will receive these alerts.

Object Inheritance is what you are looking for:

define host {
    use                     linux-host
    host_name               example
    alias                   example
    address                 10.10.10.10
    hostgroups              default-linux-services
    contact_groups          +sandradebug
}

Using the + sign, the host definition uses the data in the template and adds the sandradebug to the alerts.
