Network.AWS.CloudWatch.DescribeAlarmHistory

Retrieves the history for the specified alarm. You can filter the results by date range or item type. If an alarm name is not specified, the histories for all alarms are returned.

CloudWatch retains the history of an alarm even if you delete the alarm.

This operation returns paginated results.

Creating a Request

describeAlarmHistory :: DescribeAlarmHistory

Creates a value of DescribeAlarmHistory with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• dahAlarmName - The name of the alarm.
• dahHistoryItemType - The type of alarm histories to retrieve.
• dahEndDate - The ending date to retrieve alarm history.
• dahStartDate - The starting date to retrieve alarm history.
• dahNextToken - The token returned by a previous call to indicate that there is more data available.
• dahMaxRecords - The maximum number of alarm history records to retrieve.
