Can I get email when instance reachability check failed

Question

My instance reachability check failed for 4 days. I did not get any notification about it. Today I found my website down and reboot the instance everything is fine. But due to the long down time, Google removed my website in search results. Can I get email notification when server down?

Answer

You need to wire this up yourself:  
Setup an Email-based subscription to an SNS topic.  
Setup a CloudWatch Alarm for the metric "StatusCheckFailed"  
If the value is 1, your system or instance has failed.  
Set the notification to go to that sns topic.  
  
There is a very small charge for the alarm..something like .10/month.  
  
Good luck.
