As per the latest docs this is deprecated. This is now handled via cloudwatch itself without the need to addition mon-scripts https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/metrics-collected-by-CloudWatch-agent.html

I think answer is A, as this page suggests: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/metrics-collected-by-CloudWatch-agent.html swap_usage is monitored by CloudWatch and we don't need Custom Metrics for that.

Don't you need CloudWatch installed on the instance first?

Important The CloudWatch monitoring scripts are deprecated. We recommend that you use the CloudWatch agent to collect metrics and logs. For more information, see Collect Metrics from Amazon EC2 Instances and On-Premises Servers with the CloudWatch Agent in the Amazon CloudWatch User Guide. If you are still migrating from the deprecated monitoring scripts to the agent, and require information about the monitoring scripts, see Deprecated: Collect metrics using the CloudWatch monitoring scripts. Based on the above, scripting should be discarded

I would vote for C because the need of the CloudWatch agent installation on the EC2 instance for the custom metrics regarding the swap, but then it's confusing, why it is stated to "Run an appropriate script on a set schedule" when official documentation says that monitoring scripts are deprecated?? Is it an old question, referring to times when this kind of monitoring was done with agent + script, and now just the agent suffice? Does some the right other answer "hiddenly" assumes agent already present on the EC2 instance, even if not stated in the question? Can anyone clarify?
