Datacoral collect slices and materialized view refreshes are publishing failures as custom metrics in AWS Cloud Watch. Customers can set up notifications to their own email/slack by setting up alarms on those metrics.
Note: AWS Custom Metrics are billed separately. See AWS Custom Metrics Pricing for more details.
Custom metrics will be displayed in the AWS Console under
Custom Namespaces and
Alarms can be created from the custom metric for notifications.
Note: Make sure that your IAM role has privileges to create notification lists if a new list is needed.
