A user is trying to understand the detailed CloudWatch monitoring concept.

Which of the below mentioned services does not provide detailed monitoring with CloudWatch?
A . AWS RDS
B . AWS ELB

Answer: D

Explanation:

CloudWatch is used to monitor AWS as well as the custom services. It provides either basic or detailed monitoring for the supported AWS products. In basic monitoring, a service sends data points to CloudWatch every five minutes, while in detailed monitoring a service sends data points to CloudWatch every minute. Services, such as RDS, EC2, Auto Scaling, ELB, and Route 53 can provide the monitoring data every minute.
