Using NagCliCfg as an Ansible module.

Included in this project are the files NagCliCfg.jar, nagclicfg.yml and nagclicfg.j2

The .yml file is a sample Role for installing NagCliCfg. It makes certain assumptions about where to put stuff, if you are wanting to use Ansible I suppose you will be able to make any needed adjustments for your environment.

• Create a roles/install_nagclicfg directory on your Ansible controller machine.
• NagCliCfg.jar goes in the sub-directory roles/install_nagclicfg/files
• nagclicfg.j2 goes in the sub-directory roles/install_nagclicfg/templates
• nagclicfg.yml goes in the sub-directory roles/install_nagclicfg/tasks renamed to main.yml
• Put the following mini-script in ansible/library/nagclicfg on your Ansible controller machine and make it executable. This is so Ansible will accept a "nagclicfg" action in a task.

#!/bin/bash
/root/bin/nagclicfg $*

Here is a sample run of changing the nagiosadmin email address.

Caveat: Whenever you have NagCliCfg write the nagios configuration, the result will be "changed".

Before:

---

cat /etc/nagios/nagclicfg.d/contact.cfg 
define contact {
    host_notification_commands      notify-host-by-email
    host_notification_options       d,u,r,f,s
    host_notification_period        24x7
    name    generic-contact
    register        0
    service_notification_commands   notify-service-by-email
    service_notification_options    w,u,c,r,f,s
    service_notification_period     24x7
}
define contact {
    alias   Nagios Admin
    contact_name    nagiosadmin
    email   [email protected]
    use     generic-contact
}

---

The ansible task to change the email address:

- nagclicfg: cmds="cd /contact/nagiosadmin^set email root@localhost^write^reload"

---

Running the task:

PLAY [someservers] ************************************************************

GATHERING FACTS ***************************************************************
ok: [some-server]

TASK: [ncc-examples | Change nagiosadmin email] *******************************
changed: [some-server]

PLAY RECAP ********************************************************************
some-server : ok=2 changed=1 unreachable=0 failed=0

---

And the result, already written and with Nagios reloaded:

---

cat /etc/nagios/nagclicfg.d/contact.cfg  
define contact {
    host_notification_commands      notify-host-by-email
    host_notification_options       d,u,r,f,s
    host_notification_period        24x7
    name    generic-contact
    register        0
    service_notification_commands   notify-service-by-email
    service_notification_options    w,u,c,r,f,s
    service_notification_period     24x7
}
define contact {
    alias   Nagios Admin
    contact_name    nagiosadmin
    email   root@localhost
    use     generic-contact
}
