Notes
Note
Caution: For modules, environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. As such, files may need to be explicitly copied to the ‘host’. For lookup and connection plugins, environment variables and configuration files are read from the Ansible ‘controller’ context and not the ‘host’ context.
The AWS SDK (boto3) that Ansible uses may also read defaults for credentials and other settings, such as the region, from its configuration files in the Ansible ‘host’ context (typically
~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.

|
The dimensions for the metric. Returned: always |
|
The name of the dimension. Returned: always |
|

|
The number of periods over which data is compared to the specified threshold. Returned: always |
|
The percentile statistic for the metric associated with the alarm. Returned: always |
|
The actions to execute when this alarm transitions to an INSUFFICIENT_DATA state from any other state. Returned: always |
|
The time stamp of the last update to the alarm configuration. Returned: always |
|
Name of the monitored metric (e.g. Returned: always |
|
Name of the monitored metric (e.g. Returned: always |
|
An array of MetricDataQuery structures, used in an alarm based on a metric math expression. Returned: always |
|
Unique name for the alarm. Returned: always |
|
Name of the appropriate namespace ( Determines the category it will appear under in CloudWatch. Returned: always |
|
The actions to execute when this alarm transitions to an OK state from any other state. Returned: always |
|
The length, in seconds, used each time the metric specified in MetricName is evaluated. Valid values are 10, 30, and any multiple of 60. Returned: always |
|
An explanation for the alarm state, in text format. Returned: always |
|
The state value for the alarm. Returned: always |
|
The statistic for the metric associated with the alarm, other than percentile. Returned: always |
