A user is having data generated randomly based on a certain event. The user wants to upload that
data to CloudWatch. It may happen that event may not have data generated for some period due
to andomness. Which of the below mentioned options is a recommended option for this case?

A.
For the period when there is no data, the user should not send the data at all

B.
For the period when there is no data the user should send a blank value

C.
For the period when there is no data the user should send the value as 0

D.
The user must upload the data to CloudWatch as having no data for some period will cause an
error
at CloudWatch monitoring

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. When the user data is more random and not
generated at regular intervals, there can be a period which has no associated data. The user can
either publish the zero (0. Value for that period or not publish the data at all. It is recommended
that the user should publish zero instead of no value to monitor the health of the application. This
is helpful in an alarm as well as in the generation of the sample data count.
