A company uses Amazon Comprehend and has several custom trained models, each assigned to its own endpoint. The company wants an automated report of any endpoint that has not received traffic for over 15 days. Which AWS service can provide this monitoring capability?

Amazon CloudWatch is the correct service because it collects monitoring and operational data in the form of logs, metrics, and events. You can create custom metrics for Comprehend endpoint traffic and set up alarms to notify you if a specific endpoint's traffic metric remains at zero for over 15 days. AWS Trusted Advisor provides recommendations on cost optimization, security, and performance, but not custom operational metrics. AWS CloudTrail records API calls and related events, useful for auditing, but not for real-time traffic monitoring. AWS Config assesses, audits, and evaluates the configurations of your AWS resources, which is different from monitoring traffic patterns.
