AnsibleUndefinedVariable: 'dict object' has no attribute 'ansible_default_ipv4'" about ansible-nagios

Hey @ranjeetranjan please remove the ansible_host= from each entry and use /etc/hosts entries instead if you don't have a FQDN for them. That parameter is only used for devices that don't support SSH and Python libraries (switches, out-of-band interfaces, etc).

@sadsfae I am little confuse. Lets assume I am on 192.168.139.74.

root@mysql-conversions-1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

Please let me know what I have to remove? Or are you asking me to remove from Nagios server.

[root@nagios ansible-nagios]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

Hey @ranjeetranjan

In your Ansible hosts inventory file, remove ansible_host= directive.

Only the following inventory group entries require this (as it's used for devices without Python like out-of-band servers, PDU's, switches etc).

Unless you're using any of the below groups you have to remove the ansible_host= line after the hostname.

[switches]
[oobservers]
[idrac]
[supermicro-6048r]
[supermicro-6018r]
[supermicro-1028r]

@sadsfae SO you mean to say use like below?

[servers]
192.168.139.74

@ranjeetranjan yes, but do you have a hostname you can use? IP address may work too (I've actually never tested it). Even an /etc/hosts entry should suffice.
