We always introduce new equipment to a certain environment. One of the tasks that is required to set up a new host properly is to link it to the monitoring system. For this use case, we are going to show how to set up a Nagios agent in a Windows host and configure it from a sample configuration file:

---
- name: Setup Nagios agent on Windows hosts
  hosts: windows
  gather_facts: yes
  tasks:
   - name: Copy the MSI file for the NSClient to the 
     windows host
     win_copy:
       src: ~/win_apps/NSCP-0.5.0.62-x64.msi
       dest: C:NSCP-0.5.0.62-x64.msi

   - name: Install an NSClient with the appropriate 
     arguments
     win_msi:
       path: C:NSCP-0.5.0.62-x64.msi
       extra_args: ADDLOCAL=FirewallConfig,LuaScript,DotNetPluginSupport,Documentation,CheckPlugins,NRPEPlugins,NSCPlugins,NSCAPlugin,PythonScript,ExtraClientPlugin,SampleScripts ALLOWED_HOSTS=127.0.0.1,192.168.10.10 CONF_NSCLIENT=1 CONF_NRPE=1 CONF_NSCA=1 CONF_CHECKS=1 CONF_NSCLIENT=1 CONF_SCHEDULER=1 CONF_CAN_CHANGE=1 MONITORING_TOOL=none NSCLIENT_PWD=”N@g10sP@55w0rd”
        wait: true

   - name: Copying NSClient personalised configuration 
     file
     win_copy:
       src: ~/win_apps/conf_files/nsclient.ini
       dest: C:Program FilesNSClient++
sclient.ini

   - name: Change execution policy to allow the NSClient script remote Nagios execution
     raw: Start-Process powershell -verb RunAs -ArgumentList 'Set-ExecutionPolicy RemoteSigned -Force'

   - name: Restart the NSclient service to apply the 
     configuration change
     win_service:
       name: nscp
       start_mode: auto
       state: restarted

   - name: Delete the MSI file
     win_file: path=C:NSCP-0.5.0.62-x64.msi state=absent

This playbook can be applied to a large number of applications that can be installed using an MSI file.
