AWS provides native logging for full, near real-time visibility and transparency over the operation of your environment. These tools can integrate with monitoring solutions for end-to-end visibility and resolution of security-related activity within your IT organization. 

You can integrate your .NET Framework applications with Amazon CloudWatch by using the .NET logging frameworks listed in the following table to implement application-level logging.
