Use Amazon SNS as an alert receiver
You can use an existing Amazon SNS topic as an alert receiver for Amazon Managed Service for Prometheus, or you can create a new one. We recommend that you use a topic of the Standard type, so that you can forward alerts from the topic to email, SMS, or HTTP.
To create a new Amazon SNS topic to use as your alert manager receiver, follow the steps in Step 1: Create a topic. Be sure to choose Standard for the topic type.
If you want to receive emails every time a message is sent to that Amazon SNS topic, follow the steps in Step 2: Create a subscription to the topic.
Whether you use a new or existing Amazon SNS topic, you will need the Amazon Resource Name (ARN) of your Amazon SNS topic to complete the following tasks.
