If your nagios cmdfile is not /var/spool/nagios/cmd/nagios.cmd you
can configure ansible (on your nagios server) to use the correct
one by making a file called /etc/ansible/modules/nagios.conf that
looks like this:
-> really, we only need to exit 'couldnt' write to command file' in ONE place
[main]
cmdfile = /path/to/your/nagios.cmd
- finish up reading from a config file
When calling this module via ansible, use the 'cmdfile' parameter to
set it explicitly.
