Ansible Playbook to Check Disk Space for Windows & Linux Part -III

Here’s an updated Ansible playbook that checks the disk space on Linux CentOS, Ubuntu, and Windows in a detailed manner and writes the output to a CSV file:

- name: Check disk space and write to CSV
  hosts: all
  become: true

  tasks:
    - name: Check disk space on Linux
      block:
        - name: Check if the system is CentOS
          set_fact:
            is_centos: "{{ ansible_distribution | lower == 'centos' }}"
          ignore_errors: true
        - name: Check if the system is Ubuntu
          set_fact:
            is_ubuntu: "{{ ansible_distribution | lower == 'ubuntu' }}"
          ignore_errors: true
        - name: Check disk space on CentOS
          command: df -hT
          when: is_centos | bool
          register: centos_disk_space
        - name: Check disk space on Ubuntu
          command: df -hT
          when: is_ubuntu | bool
          register: ubuntu_disk_space
        - name: Print disk space on CentOS
          debug:
            msg: "{{ centos_disk_space.stdout_lines }}"
          when: is_centos | bool
        - name: Print disk space on Ubuntu
          debug:
            msg: "{{ ubuntu_disk_space.stdout_lines }}"
          when: is_ubuntu | bool
        - name: Write disk space to CSV file on CentOS
          when: is_centos | bool
          local_action:
            module: csv_writer
            path: "{{ inventory_hostname }}-disk-space.csv"
            headers: ['Filesystem', 'Type', 'Size', 'Used', 'Available', 'Use%', 'Mounted on']
            content: "{{ centos_disk_space.stdout_lines[1:] }}"
        - name: Write disk space to CSV file on Ubuntu
          when: is_ubuntu | bool
          local_action:
            module: csv_writer
            path: "{{ inventory_hostname }}-disk-space.csv"
            headers: ['Filesystem', 'Type', 'Size', 'Used', 'Available', 'Use%', 'Mounted on']
            content: "{{ ubuntu_disk_space.stdout_lines[1:] }}"
      when: "ansible_os_family == 'RedHat' or ansible_os_family == 'Debian'"

    - name: Check disk space on Windows
      block:
        - name: Check disk space on Windows
          win_shell: Get-Volume | Select-Object -Property DriveLetter, FileSystemLabel, FileSystem, SizeRemaining, Size | ConvertTo-Csv -NoTypeInformation
          register: windows_disk_space
        - name: Print disk space on Windows
          debug:
            msg: "{{ windows_disk_space.stdout_lines }}"
        - name: Write disk space to CSV file on Windows
          local_action:
            module: copy
            content: "{{ windows_disk_space.stdout }}"
            dest: "{{ inventory_hostname }}-disk-space.csv"
      when: ansible_os_family == 'Windows'

Here’s what’s changed in this playbook:

• We added two new tasks to write the disk space information to a CSV file using the csv_writer module (for Linux) and copy module (for Windows).
• We added a headers option to specify the headers for the CSV file.
• We removed the ignore_errors option from the set_fact tasks since we want them to fail if the distribution is not CentOS or Ubuntu.

Note that the CSV file will be created in the same directory where you run the Ansible playbook from. You can modify the path option to specify a different directory if needed.
