Create Amazon CloudWatch alarms to monitor Amazon Direct Connect connections

You can create a CloudWatch alarm that sends an Amazon SNS message when the alarm changes state. An alarm watches a single metric over a time period that you specify. It sends a notification to an Amazon SNS topic based on the value of the metric relative to a given threshold over a number of time periods.

For example, you can create an alarm that monitors the state of an Amazon Direct Connect connection. It sends a notification when the connection state is down for five consecutive 1-minute periods. For details on what to know for creating an alarm and for more information on creating an alarm, see Using Amazon CloudWatch Alarms in the Amazon CloudWatch User Guide.
