module: rax_mon_notification_plan
short_description: Create or delete a Rackspace Cloud Monitoring notification
                   plan.
description:
  - Create or delete a Rackspace Cloud Monitoring notification plan by
    associating existing rax_mon_notifications with severity levels. Rackspace
    monitoring module flow | rax_mon_entity -> rax_mon_check ->
    rax_mon_notification -> *rax_mon_notification_plan* -> rax_mon_alarm.
  - This module relies on the C(pyrax) package which is deprecated in favour of using Openstack API.
  - Unless maintainers step up to work on the module, it will be marked as deprecated in community.general 7.0.0 and removed in version 9.0.0.
options:
  state:
    type: str
    description:
    - Ensure that the notification plan with this C(label) exists or does not
      exist.
    choices: ['present', 'absent']
    default: present
  label:
    type: str
    description:
    - Defines a friendly name for this notification plan. String between 1 and
      255 characters long.
    required: true
  critical_state:
    type: list
    elements: str
    description:
    - Notification list to use when the alarm state is CRITICAL. Must be an
      array of valid rax_mon_notification ids.
  warning_state:
    type: list
    elements: str
    description:
    - Notification list to use when the alarm state is WARNING. Must be an array
      of valid rax_mon_notification ids.
  ok_state:
    type: list
    elements: str
    description:
    - Notification list to use when the alarm state is OK. Must be an array of
      valid rax_mon_notification ids.
