title: Add EC2 Action to Cloudwatch Alarm on health check
body: <p>I have an AWS bitnami instance that I've created a Route 53 health check alarm when the website it becomes unavailable. The first action triggers successfully and sends me an email. However, I would also like for the instance to be rebooted, although the Add EC2 action is greyed out and it reads: "This action is only available for EC2 Per-Instance Metrics". How can I add this?</p>

  <p>Could it be related to this: My EC2 instance exists in the Ireland AZ, but and when I create the alarm and SNS topic on the health check in Route 53 it automatically creates them in the N.Virginia AZ. And I don't appear to have access to changing where this goes.</p>
