As I wrote some time ago, I was trying to utilize Nagios 3.x’s neat feature of “nested” hostgroups. Well, as it turned out I thought it worked differently; basically like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
define hostgroup { hostgroup_name a-parent-hostgroup alias Our toplevel parent hostgroup } define service { use generic-service check_command check_dummy!0! service_description SSH hostgroup_name a-parent-hostgroup } define hostgroup { hostgroup_name a-child-hostgroup hostgroup_members a-parent-hostgroup alias Our child hostgroup } define service { use generic-service check_command check_dummy!0! service_description LOAD hostgroup_name a-child-hostgroup } |
As you can cleary see on line 14, I thought you define the relation between two hostgroups in the child hostgroup. The problem with it was basically (as I said in the earlier posts), that all the services defined for the child hostgroups are handed on upwards to the parent hostgroup(s).
But after talking to Tobi, I quickly found out, that the relation is in fact defined within the parent hostgroup. So if you simply put hostgroup_members within the parent hostgroup and define all child hostgroups which should inherit from the parent one, you should be just fine.
