Before resorting to Synthetics, you can use Cloudwatch to setup anomaly reporting on the load balancer. If your requests drop to 0 in 5/10/15 minutes, alert... If you have more than N 500s in 5/10/15 minutes, alert.

Synthetics are there to tell you when something outside of your provider is breaking your website, like routing errors, geo-related issues, CDN issues (assuming you're not using your provider's CDN).
