A company runs an application on Amazon EC2 instances. The EC2 instances are in an Auto Scaling group and run behind an Application Load Balancer (ALB). The application experiences errors when total requests exceed 100 requests per second. A SysOps administrator must collect information about total requests for a 2-week period to determine when requests exceeded this threshold.
What should the SysOps administrator do to collect this data?

A. Use the ALB’s RequestCount metric. Configure a time range of 2 weeks and a period of 1 minute. Examine the chart to determine peak traffic times and volumes.

B. Use Amazon CloudWatch metric math to generate a sum of request counts for all the EC2 instances over a 2-week period. Sort by a 1-minute interval.

C. Create Amazon CloudWatch custom metrics on the EC2 launch configuration templates to create aggregated request metrics across all the EC2 instances.

D. Create an Amazon EventBridge (Amazon CloudWatch Events) rule. Configure an EC2 event matching pattern that creates a metric that is based on EC2 requests. Display the data in a graph.
