Objects are defined in yaml files, and converted to configuration files from templates.
You can view more details for variables in default/main folder
Variables defined per Operative System are defined in vars/ folder.
Replace the default values in vars.yaml file, and encrypt this file.
To modify variable data, copy the folder nagios located inside of main folder to your local inventory folder, preferably in the group_vars/ or host_vars/ folder
Hosts and services could be defined in one variable or per file.
In localhost.yaml you will find an example to define new hosts.
Copy files/nagios folder in your prefered.
You can create files per host to define host and services. Create the folder
and update variable to indicate the path location for files.
# nagios_hosts_path: inventory/nagios_hosts
On inventory folder creates a file like this:
_host:
host_name: hostname #required
address: 192.168.0.1 #if is not defined, is replaced by the name
alias: Server Description
use: template #if is not defined, nagios_host_template_default var is the default template
_services:
servicename: servicecommand!arguments # is defined with 'nagios_service_template_default' as service template
servicename-other:
use: service_template
check_command: servicecommand!arguments!arguments #syntax: <command_name>!$ARG1$!$ARG2$
#check the commands.yaml file to validate the servicecommand and parameters
Define the hostgroups and servicegroups in nagios_hostgroups
and nagios_servicegroups
variables,
then you can add if one host and service belongs in there.
Check the contacts.yaml to get more details about variables.
To ensure the user was deleted from httpasswd file, add the data state: absent
on the contact definition,
the user will be deleted from contacts definition and the htpasswd file.
Contact groups are the best way to handle notifications, create a contact, and join groups. If a contact_group is defined on the host, all services inherit the same contact group, or you can define one contact group per service
