AWS Trusted Advisor is a new feature in the AWS Management Console that provides best practice recommendations for optimizing cost, performance, security, and fault tolerance through four core checks. The Service Limits Check gives granular resource consumption data across different AWS services. Integrating Trusted Advisor with Datadog allows users to monitor these metrics on an out-of-the-box dashboard, enabling quicker optimization of resources and infrastructure scaling. With this integration, users can set up custom monitors and alerts for unexpected changes in resource consumption, providing more precise control over service resource usage. Setting up Trusted Advisor with Datadog is simple and provides valuable insights into AWS performance and usage.
