AWS Certified SysOps Administrator SOA-C01 – Question437

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

A. Create one csv file of all the data and send a single file to CloudWatch
B. Aggregate the data with statistics, such as Min, max, Average, Sum and Sample data and send the data to CloudWatch
C. 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
D. Send all the data values to CloudWatch in a single command by separating them with a comma. CloudWatch will parse automatically

Correct Answer: B

Explanation:

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. Reference:
