StateValue
differs from the previous value, the action configured for the appropriate state is
invoked. For example, if your alarm is configured to send an Amazon SNS message when
an alarm is triggered, temporarily changing the alarm's state to ALARM will
send an Amazon SNS message. This is not a permanent change. The next periodic alarm
check (in about a minute) will set the alarm to its actual state. Because the alarm
state change happens very quickly, it is typically only visibile in the alarm's History
tab in the Amazon CloudWatch console or through DescribeAlarmHistory
.
