Web application failed request monitoring

Question

Hi,  
  
First post so hopefully I will give you enough information.  
  
We have a web application in Elixir that uses API's and we require the ability to monitor any failed requests. API servers (Custom instances in Ubuntu) are behind a standard load balancer and connect to an RDS database.  
  
First question is; we know application trace monitoring is available in tools like Datadog etc but i wonder if it is possible to use Cloudwatch in any way. I am aware of the standard metrics with in CW but wondered if there is a way to extend so that i can monitor any failed attempts or API calls?  
  
Second question if the answer to the first is "Yes", how?  
  
Thanks in advance

Hi There,  
  
We recently launched CloudWatch ServiceLens that helps you gain observability into application performance using metrics, logs, and traces. This can help you view the faults or errors associated with the requests flowing through your services. You can learn more here: https://aws.amazon.com/about-aws/whats-new/2019/11/announcing-amazon-cloudwatch-servicelens/  
  
You an also learn how to get started here:

If you intend to monitor endpoints such as APIs, URLs by creating synthetic traffic, you can also use the newly previewed CloudWatch Synthetics. You can learn more here: https://aws.amazon.com/about-aws/whats-new/2019/11/introducing-amazon-cloudwatch-synthetics-preview/
