CloudWatch SMS notifications for EC2 instances that are not in us-east-1


I am looking to get a notification schema setup for my EC2 instances that are in the us-west-2 data center. I have read the CloudWatch and SNS docs, and I am aware that SMS notifications are only available when setting up SNS Topics in us-east-1.

I am wondering if anyone has found a way to get CloudWatch alarms for instances NOT in us-east-1 to broadcast on a topic setup in us-east-1?


It appears that the documentation is incorrect – when trying to add a new alarm in us-west-2 that points at a topic in us-east-1 for the SMS capabilities, the following error is observed (tried this today on Sept 10 2014):

This is based on running the following command using the aws cli (account number changed to 1234567890):

I guess the previous answer was from somebody who didn’t actually test this out… It’s that or AWS disabled the ability to reference other region sns topics in the last few months and forgot to update their documentation…
