AWS CloudWatch Web Server Metrics

Question

I have a few EC2 instances with NGINX installed using both ports 80 and 443. The instances are serving different applications so I'm not using an ELB.

I would like to create a CloudWatch alarm to make sure port 80 is always returning 200 HTTP status code. I realize there are several commercial solutions for this such as New Relic, etc, but this is the task I have at hand at the moment.

look into Route53 health checks. You might get away with just configuring a health check there if you are already using Route53:http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/dns-failover.html
