A user is publishing custom metrics to CloudWatch. Which of the below mentioned statements will help the
user understand the functionality better?

A.
The user can use the CloudWatch Import tool

B.
The user should be able to see the data in the console after around 15 minutes

C.
If the user is uploading the custom data, the user must supply the namespace, timezone, and metric name
as part of the command

D.
The user can view as well as upload data using the console, CLI and APIs

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 has to always include the namespace as a part of the request.
However, the other parameters are optional. If the user has uploaded data using CLI, he can view it as a graph
inside the console. The data will take around 2 minutes to upload but can be viewed only after around 15
minutes.
