alarmTypes

Use this parameter to specify whether you want the operation to return metric alarms or composite alarms. If you omit this parameter, only metric alarms are returned, even if composite alarms exist in the account.

For example, if you omit this parameter or specify MetricAlarms, the operation returns only a list of metric alarms. It does not return any composite alarms, even if composite alarms exist in the account.

If you specify CompositeAlarms, the operation returns only a list of composite alarms, and does not return any metric alarms.
