A user is collecting 1000 records per second. The user wants to send the data to CloudWatch using the
custom namespace. Which of the below mentioned options is recommended for this activity?

A.
Aggregate the data with statistics, such as Min, max, Average, Sum and Sample data and send the data to
CloudWatch

B.
Send all the data values to CloudWatch in a single command by separating them with a comma.
CloudWatch will parse automatically

C.
Create one csv file of all the data and send a single file to CloudWatch

D.
It is not possible to send all the data in one call. Thus, it should be sent one by one. CloudWatch will
aggregate the data automatically

Explanation:
AWS CloudWatch supports the custom metrics. The user can always capture the custom data and upload the
data to CloudWatch using CLI or APIs. The user can publish data to CloudWatch as single data points or as an
aggregated set of data points called a statistic set using the command put-metric-data. It is recommended that
when the user is having multiple data points per minute, he should aggregate the data so that it will minimize
the number of calls to put-metric-data. In this case it will be single call to CloudWatch instead of 1000 calls if
the data is aggregated.
