AWS Certified SysOps Administrator – Associate (legacy) — Question 416

Is it possible to publish your own metrics to CloudWatch?

Answer options

• A. Yes, but only if the data is aggregated.
• B. No, it is not possible.
• C. No, metrics are in-built and cannot be defined explicitly.
• D. Yes, it can be done by using the put-metric-data command.

Correct answer: D

Explanation

Amazon CloudWatch allows you to publish your own custom metrics using the AWS CLI or API. The put-metric-data command is specifically designed to upload these user-defined data points to CloudWatch. Built-in metrics are not the only option, and pre-aggregation is not a requirement for publishing.
