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

A.
It is not possible to setup detailed monitoring for Auto Scaling

B.
In this case, Auto Scaling will send data every minute and will charge the user extra

C.
Detailed monitoring will send data every minute without additional charges

D.
Auto Scaling sends data every minute only and does not charge the user

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. Auto Scaling includes 7 metrics and 1 dimension, and sends data to
CloudWatch every 5 minutes by default. The user can enable detailed monitoring for Auto Scaling,
which sends data to CloudWatch every minute. However, this will have some extra-costs.
