####ossec_server_config: At first, there is the server configuration. Change it for your needs, as this default setup won't do any good for you. (You don't have access to use the mail.example.com mailhost. :-))

####ossec_agent_configs: http://ossec-docs.readthedocs.org/en/latest/manual/agent/agent-configuration.html

There are 3 "types":

• os
• name
• profile

In the above setup, the type is os. And this configuration is for the "linux" os. You can have several types configured in the host_vars file, so you can create all kind of different configs.

You can find here some more information about the ossec shared agent configuration: http://ossec-docs.readthedocs.org/en/latest/manual/syscheck/

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: ossec-server.example.com
  roles:
     - { role: ansible-wazuh-manager }
