DeleteAlarms
Deletes the specified alarms. You can delete up to 100 alarms in one operation. However, this total can include no more than one composite alarm. For example, you could delete 99 metric alarms and one composite alarms with one operation, but you can't delete two composite alarms with one operation.
If you specify an incorrect alarm name or make any other error in the operation,
no alarms are deleted. To confirm that alarms were deleted successfully, you can use the
DescribeAlarms operation after using DeleteAlarms.
Note
It is possible to create a loop or cycle of composite alarms, where composite alarm A depends on composite alarm B, and composite alarm B also depends on composite alarm A. In this scenario, you can't delete any composite alarm that is part of the cycle because there is always still a composite alarm that depends on that alarm that you want to delete.
To get out of such a situation, you must break the cycle by changing the rule of
one of the composite alarms in the cycle to remove a dependency that creates the
cycle. The simplest change to make to break a cycle is to change the
AlarmRule of one of the alarms to false.
Additionally, the evaluation of composite alarms stops if CloudWatch detects a cycle in the evaluation path.
