A company deployed an application as a set of microservices that run on Amazon Elastic Container Service (Amazon ECS) behind an Application Load Balancer (ALB). The performance of the microservices has started to degrade for a specific set of user requests. The company needs to gain deeper insight into the request behavior that is associated with the performance degradation.
Which process will meet this requirement?

A. Create a Docker image that runs the AWS X-Ray daemon. Run the image alongside the microservices in Amazon ECS. Use the X-Ray console to view requests to the microservices.

B. Perform distributed tracing based on the ALB's built-in traffic request metrics.

C. Use Amazon CloudWatch to collect metrics and logs from Amazon ECS. Perform distributed tracing based on the ECS metrics and logs.

D. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to capture the ECS metrics and logs. Use the EventBridge console to view the requests to the microservices.
