A SysOps administrator is responsible for monitoring the performance of Amazon Elastic Block Store (Amazon EBS) volumes attached to a fleet of Amazon EC2 instances. The administrator has set up Amazon CloudWatch alarms for the DiskReadBytes and DiskWriteBytes metrics, which will be used when the I/O activity exceeds a certain threshold. There’s also a custom Python-based monitoring tool installed that checks the I/O performance.

During a recent incident, the Python tool reported that there were elevated read and write operations, but the CloudWatch alarms did not transition into an ALARM state. The administrator verified that the alarm configurations were correct in CloudWatch. The custom monitoring tool has also been verified to be working fine.

What solution should be implemented to ensure that the alarms for volume I/O metrics work as expected and trigger alerts during incidents?

You state correct answer is

Modify the existing Amazon CloudWatch Alarms to use the

VolumeReadBytes and VolumeWriteBytes metrics to monitor the EBS volumes.

It makes no sense for that to work as it doesnt say anywhere that python script is monitoring Volumes…
