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.
