A user is trying to understand the CloudWatch metrics for the AWS services. It is required that the user should first understand the namespace for the AWS services. Which of the below mentioned is not a valid namespace for the AWS services? A. AWS/StorageGateway B. AWS/CloudTrail C. AWS/ElastiCache D. AWS/SWF
Correct Answer: B
Explanation:
Explanation: Amazon CloudWatch is basically a metrics repository. The AWS product puts metrics into this repository, and the user can retrieve the data or statistics based on those metrics. To distinguish the data for each service, the CloudWatch metric has a namespace. Namespaces are containers for metrics. All AWS services that provide the Amazon CloudWatch data use a namespace string, beginning with “AWS/”. All the services which are supported by CloudWatch will have some namespace. CloudWatch does not monitor CloudTrail. Thus, the namespace “AWS/CloudTrail” is incorrect.
