Network.AWS.CloudWatch.DescribeAlarmHistory

Retrieves history for the specified alarm. Filter alarms by date range or item type. If an alarm name is not specified, Amazon CloudWatch returns histories for all of the owner's alarms.

Amazon CloudWatch retains the history of an alarm for two weeks, whether or not you delete the alarm.

This operation returns paginated results.
