Hello friends  
maybe a noob question but I’m unable to get host variable work as expected. This is my question.

Given this template:

object Host “{{ hostvars[item][‘ansible\_fqdn’] }}” {  
import “generic-host”  
address = “{{ hostvars[item][‘ansible\_eth0’][‘ipv4’][‘address’] }}”  
vars.os = “Linux”  
vars.sla = “24x7”  
vars.http = “yes”  
vars.smtp = “yes”  
}

generated by this task:

- name: Copy Host Definitions  
template: src=host\_def.j2  
dest={{ icinga2\_hosts\_dir }}{{ hostvars[item][‘ansible\_fqdn’] }}.conf  
owner=root  
group=root  
mode=0644  
with\_items: groups[‘monitored’]  
notify:
- restart icinga2

How I can access an host variable eventually defined in inventory?

[monitored:children]  
myservers

[myserver]  
host1 vars\_http=no

What I want to do is something like this:

object Host “{{ hostvars[item][‘ansible\_fqdn’] }}” {  
import “generic-host”  
address = “{{ hostvars[item][‘ansible\_eth0’][‘ipv4’][‘address’] }}”  
vars.os = “Linux”  
vars.sla = “24x7”  
{% if vars\_http == “no” %}  
vars.http = “no”  
{% else %}  
vars.http = “yes”  
{% endif %}  
vars.smtp = “yes”  
}

Thanks for support.

Since you appear to be walking over “hostvars” are you trying to have a template that includes the variables for every host in a certain group?

If so, we know how to do that.

Let us know.
