Network.AWS.CloudWatch.DescribeAlarms

Retrieves the specified alarms. If no alarms are specified, all alarms are returned. Alarms can be retrieved by using only a prefix for the alarm name, the alarm state, or a prefix for any action.

This operation returns paginated results.

Creating a Request

describeAlarms :: DescribeAlarms

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

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

• daAlarmNamePrefix - The alarm name prefix. If this parameter is specified, you cannot specify AlarmNames .
• daActionPrefix - The action name prefix.
• daNextToken - The token returned by a previous call to indicate that there is more data available.
• daStateValue - The state value to be used in matching alarms.
• daAlarmNames - The names of the alarms.
• daMaxRecords - The maximum number of alarm descriptions to retrieve.
