[All AWS Certified SysOps Administrator - Associate Questions]

A company has a web application that is experiencing performance problems many times each night. A root cause analysis reveals sudden increases in CPU utilization that last 5 minutes on an Amazon EC2 Linux instance. A SysOps administrator must find the process ID (PID) of the service or process that is consuming more CPU.
What should the SysOps administrator do to collect the process utilization information with the LEAST amount of effort?

A. Configure the Amazon CloudWatch agent procstat plugin to capture CPU process metrics.
B. Configure an AWS Lambda function to run every minute to capture the PID and send a notification.
C. Log in to the EC2 instance by using a .pem key each night. Then run the top command.
D. Use the default Amazon CloudWatch CPU utilization metric to capture the PID in CloudWatch.

A The procstat plugin enables you to collect metrics from individual processes. It is supported on Linux servers and on servers running Windows Server 2012 or later. https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Agent-procstat-process-metrics.html

Selected Answer: A

The procstat plugin allows monitoring of specific processes based on criteria such as process name, command line, or user. This means you can capture CPU utilization data and PIDs for the processes causing high CPU usage.

Option D: The default Amazon CloudWatch CPU utilization metric already provides aggregated data on CPU usage for the EC2 instance. It requires no additional configuration or setup. While it doesn’t directly provide the specific process ID (PID), it’s the simplest and least effort-intensive approach.

This is not true as the easiest way will be to use the procstat plugin by configuring on the CloudWatch agent. It will collect data and metrics for each individual process on your EC2 instance. So the correct option is A.
