module: clc_alert_policy
short_description: Create or Delete Alert Policies at CenturyLink Cloud.
description:
- An Ansible module to Create or Delete Alert Policies at CenturyLink Cloud.
options:
alias:
description:
- The alias of your CLC Account
type: str
required: True
name:
description:
- The name of the alert policy. This is mutually exclusive with id
type: str
id:
description:
- The alert policy id. This is mutually exclusive with name
type: str
alert_recipients:
description:
- A list of recipient email ids to notify the alert.
This is required for state 'present'
type: list
metric:
description:
- The metric on which to measure the condition that will trigger the alert.
This is required for state 'present'
type: str
choices: ['cpu','memory','disk']
duration:
description:
- The length of time in minutes that the condition must exceed the threshold.
This is required for state 'present'
type: str
threshold:
description:
- The threshold that will trigger the alert when the metric equals or exceeds it.
This is required for state 'present'
This number represents a percentage and must be a value between 5.0 - 95.0 that is a multiple of 5.0
type: int
state:
description:
- Whether to create or delete the policy.
type: str
default: present
choices: ['present','absent']
requirements:
- python = 2.7
- requests >= 2.5.0
- clc-sdk
author: "CLC Runner (@clc-runner)"
notes:
- To use this module, it is required to set the below environment variables which enables access to the
Centurylink Cloud
- CLC_V2_API_USERNAME, the account login id for the centurylink cloud
- CLC_V2_API_PASSWORD, the account password for the centurylink cloud
- Alternatively, the module accepts the API token and account alias. The API token can be generated using the
CLC account login and password via the HTTP api call @ https://api.ctl.io/v2/authentication/login
- CLC_V2_API_TOKEN, the API token generated from https://api.ctl.io/v2/authentication/login
- CLC_ACCT_ALIAS, the account alias associated with the centurylink cloud
- Users can set CLC_V2_API_URL to specify an endpoint for pointing to a different CLC environment.
