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.
D
-Auto Scaling groups: seven pre-selected metrics at one-minute frequency, optional and for no additional charge.
-Elastic Load Balancers: thirteen pre-selected metrics at one-minute frequency, for no additional charge.
-Amazon Route 53 health checks: One pre-selected metric at one-minute frequency, for no additional charge.
