module: ovirt_quota_facts
short_description: Retrieve information about one or more oVirt/RHV quotas
author: "Maor Lipchuk (@machacekondra)"
deprecated:
    removed_in: 3.0.0  # was Ansible 2.13
    why: When migrating to collection we decided to use only _info modules.
    alternative: Use M(ovirt.ovirt.ovirt_quota_info) instead.
description:
    - "Retrieve information about one or more oVirt/RHV quotas."
notes:
    - "This module returns a variable C(ovirt_quotas), which
       contains a list of quotas. You need to register the result with
       the I(register) keyword to use it."
options:
    data_center:
        description:
            - "Name of the datacenter where quota resides."
        required: true
    name:
        description:
            - "Name of the quota, can be used as glob expression."
extends_documentation_fragment:
- community.general.ovirt_facts

'''

EXAMPLES = '''
# Examples don't contain auth parameter for simplicity,
# look at ovirt_auth module to see how to reuse authentication:

- name: Gather information about quota named C<myquota> in Default datacenter
  ovirt_quota_info:
    data_center: Default
    name: myquota
  register: result

- name: Print gathered information
  ansible.builtin.debug:
    msg: "{{ result.ovirt_quotas }}"
'''

RETURN = '''
ovirt_quotas:
    description: "List of dictionaries describing the quotas. Quota attributes are mapped to dictionary keys,
                  all quotas attributes can be found at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/quota."
    returned: On success.
