text message, or a call to an HTTP endpoint. For example, all regions support email notifications, but
SMS notifications can only be created in the US East (N. Virginia) region.
When you create an event notification subscription, you specify one or more event filters. Amazon Redshift
sends notifications through the subscription any time an event occurs that matches all of the filter criteria.
The filter criteria include source type (such as cluster or snapshot), source ID (such as the name of a
cluster or snapshot), event category (such as Monitoring or Security), and event severity (such as INFO
or ERROR).
You can easily turn off notification without deleting a subscription by setting the Enabled radio button to
No in the AWS Management Console or by setting the Enabled parameter to false using the Amazon
Redshift CLI or API.
Billing for Amazon Redshift event notification is through the Amazon Simple Notification Service (Amazon
SNS). Amazon SNS fees apply when using event notification; for more information on Amazon SNS
billing, go to Amazon Simple Notification Service Pricing.
You can also view Amazon Redshift events that have occurred by using the management console. For
more information, see Amazon Redshift Events (p. 199).
Subscribing to Amazon Redshift Event Notifications
You can create an Amazon Redshift event notification subscription so you can be notified when an event
occurs for a given cluster, snapshot, security group, or parameter group. The simplest way to create a
subscription is with the Amazon SNS console. For information on creating an Amazon SNS topic and
subscribing to it, see Getting Started with Amazon SNS.
You can create an Amazon Redshift event notification subscription so you can be notified when an event
occurs for a given cluster, snapshot, security group, or parameter group. The simplest way to create a
subscription is with the AWS Management Console. If you choose to create event notification subscriptions
using the CLI or API, you must create an Amazon Simple Notification Service topic and subscribe to that
topic with the Amazon SNS console or Amazon SNS API.You will also need to retain the Amazon
Resource Name (ARN) of the topic because it is used when submitting CLI commands or API actions.
For information on creating an Amazon SNS topic and subscribing to it, see Getting Started with Amazon
SNS.
An Amazon Redshift event subscription can specify these event criteria:
• Source type, the values are cluster, snapshot, parameter-groups, and security-groups.
• Source ID of a resource, such as my-cluster-1 or my-snapshot-20130823.The ID must be for a
resource in the same region as the event subscription.
• Event category, the values are Configuration, Management, Monitoring, and Security.
• Event severity, the values are INFO or ERROR.
The event criteria can be specified independently, except that you must specify a source type before you
can specify source IDs in the console. For example, you can specify an event category without having
to specify a source type, source ID, or severity. While you can specify source IDs for resources that are
not of the type specified in source type, no notifications will be sent for events from those resources. For
example, if you specify a source type of cluster and the ID of a security group, none of the events raised
by that security group would match the source type filter criteria, so no notifications would be sent for
those events.
Amazon Redshift sends a notification for any event that matches all criteria specified in a subscription.
