A user has setup a web application on EC2. The user is generating a log of the application
performance at every second. There are multiple entries for each second. If the user wants to
send that data to CloudWatch every minute, what should he do?

A.
The user should send only the data of the 60th second as CloudWatch will map the receive
data
timezone with the sent data timezone

B.
It is not possible to send the custom metric to CloudWatch every minute

C.
Give CloudWatch the Min, Max, Sum, and SampleCount of a number of every minute

D.
Calculate the average of one minute and send the data to CloudWatch

Explanation:
Amazon CloudWatch aggregates statistics according to the period length that the user has
specified while
getting data from CloudWatch. The user can publish as many data points as he wants with the
same or similartime stamps. CloudWatch aggregates them by the period length when the user
calls get statistics about those data points. CloudWatch records the average (sum of all items
divided by the number of items. of the values received for every 1-minute period, as well as the
number of samples, maximum value, and minimum value for the same time period. CloudWatch
will aggregate all the data which have time stamps within a one-minute period.
