+Extra info regarding: ansible_fqdn problematic for getting hostname #105
+
+*Describe the bug*
+
+In some nodes I'm getting weird hostnames, mostly localhost.localdomain. Those nodes show proper configuration in hostnamectl. I've seen you're using 'ansible_fqdn' as default.

+Seems like ansible_fqdn and ansible_hostname can give different results, and sometimes even very weird results, as it sometimes makes DNS calls (which is not under my control in that cases) to infer that names.
+
+*Fix proposal*
+
+In my playbook I've added this parameter:
+
+	telegraf_agent_hostname: "{{ ansible_nodename }}"
