For new projects, we recommend that you use the new Managed Service for Apache Flink Studio over Kinesis Data Analytics for SQL Applications. Managed Service for Apache Flink Studio combines ease of use with advanced analytical capabilities, enabling you to build sophisticated stream processing applications in minutes.

Creating CloudWatch Alarms to Monitor

You can create an Amazon CloudWatch alarm that sends an Amazon SNS message when the alarm changes state. An alarm watches a single metric over a time period you specify. It performs one or more actions based on the value of the metric relative to a given threshold over a number of time periods. The action is a notification sent to an Amazon SNS topic or Auto Scaling policy.

Alarms invoke actions for sustained state changes only. For a CloudWatch alarm to invoke an action, the state must have changed and been maintained for a specified amount of time.

You can set alarms using the AWS Management Console, CloudWatch AWS CLI, or CloudWatch API, as described following.

To set an alarm using the CloudWatch console
  1. Sign in to the AWS Management Console and open the CloudWatch console at

  2. Choose Create Alarm. The Create Alarm Wizard starts.

  3. Choose Kinesis Analytics Metrics. Then scroll through the metrics to locate the metric you want to place an alarm on.

    To display just metrics, search for the file system ID of your file system. Choose the metric to create an alarm for, and then choose Next.

  4. Enter values for Name, Description, and Whenever for the metric.

  5. If you want CloudWatch to send you an email when the alarm state is reached, in the Whenever this alarm: field, choose State is ALARM. In the Send notification to: field, choose an existing SNS topic. If you select Create topic, you can set the name and email addresses for a new email subscription list. This list is saved and appears in the field for future alarms.


    If you use Create topic to create a new Amazon SNS topic, the email addresses must be verified before they receive notifications. Emails are only sent when the alarm enters an alarm state. If this alarm state change happens before the email addresses are verified, they do not receive a notification.

  6. In the Alarm Preview section, preview the alarm you’re about to create.

  7. Choose Create Alarm to create the alarm.
