print free space for mount

[Nicholas Britton]

I am trying to print the free space for a mount that an application needs to have x free on.   Once i can do that i would look at adding actions based on that, but i would also like to the user running the play to know if there is an issue or not.   

Here is what i have so far, and i cant see to get what i would expect, any thoughts:

code:

---

- hosts: all

  tasks:

    - debug:

        msg: "Mount Point {{item.mount}} free space {{item.size_available/1073741824}} "

      loop: "{{ansible_mounts}}"

      when: item.mount == '/home'

output:

PLAY [all] **********************************************************************************************************************************************************

TASK [Gathering Facts] **********************************************************************************************************************************************

ok: [server]

TASK [debug] ********************************************************************************************************************************************************

skipping: [server] => (item={u'block_used': 3056865, u'uuid': u'bf9d7ab9-4be3-419d-8aed-f3b952b75957', u'size_total': 84408975360, u'block_total': 20607660, u'mount': u'/', u'block_available': 17550795, u'size_available': 71888056320, u'fstype': u'ext4', u'inode_total': 5242880, u'inode_available': 5165347, u'device': u'/dev/mapper/VolGroup-lv_root', u'inode_used': 77533, u'block_size': 4096, u'options': u'rw'})

    "msg": "Mount Point /home free space 86.5906448364 "

}

What i really want to display and only display is : "Mount Point /home free space 86.5906448364 "

Then you would need to write you own callback plugin or try the included ones to see if have output you like
