In an AWS autoscaling group, I can configure notifications for instance launch and terminate actions and error variations of the 2, but is there any way to configure a notification when a group is created / destroyed?

If you are using AWS SNS, and you have subscribed to a topic, you will receive it's notifications based on the actions, or you could use lifecycle notifications as stated in this document.– Alin AndreiOct 3, 2016 at 9:48

I'm using SNS. I get a test notification when a group is created and notifications for instances starting and being terminated. But there is no "Group is being shut down" notification - all notifications besides the test are instance-centric, not group-centric. In the same way, ASG lifecycle hooks are based on INSTANCE lifecycle phases and do not alert to GROUPS being created / destroyed.– BrettOct 3, 2016 at 9:56

This is weird indeed, after some researching, it seems ASG doesn't send notification if the group is being shut down only the ec2 instances, do you have cloud trail enabled ? can you see if there anything there regarding ASG ?– Alin AndreiOct 3, 2016 at 12:22

Ah yes, thanks for the suggestion Alin - looking into that now.– BrettOct 3, 2016 at 13:28

As mentioned in the comments, there is no way to have the ASG itself notify you.
You would need to have a cloudwatch event trigger off of the DeleteAutoScaling Group or CreateAutoScalingGroup API calls.
From the Cloudwatch events console: - Create Rule - Select Auto Scaling as the service - AWS API Call via CloudTrail - Specific operation(s) - The API calls you want - Add an SNS topic as the target
