A user has configured an Auto Scaling group with ELB. The user has enabled detailed
CloudWatch monitoring on Elastic Load balancing. Which of the below mentioned statements will
help the user understand this functionality better?

B.

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. Elastic Load Balancing includes 10 metrics and 2 dimensions, and
sends data to CloudWatch every minute. This does not cost extra.
