A user has created an Auto Scaling group using CLI. The user wants to enable CloudWatch
detailed
monitoring for that group. How can the user configure this?

A.
When the user sets an alarm on the Auto Scaling group, it automatically enables detail
monitoring

B.
By default detailed monitoring is enabled for Auto Scaling

C.
Auto Scaling does not support detailed monitoring

D.
Enable detail monitoring from the AWS console

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. To enable detailed instance monitoring for a new Auto Scaling group,
the user does not need to take any extra steps. When the user creates an Auto Scaling launch
config as the first step for creating an Auto Scaling group, each launch configuration contains a
flag named
InstanceMonitoring.Enabled. The default value of this flag is true. Thus, the user does not need to
set this flag if he wants detailed monitoring.
