Exam AWS-SysOps topic 1 question 873 discussion

Exam question from Amazon's AWS-SysOps
Question #: 873
Topic #: 1
[All AWS-SysOps Questions]

A company has a web application that is experiencing performance problems many times each night. A root cause analysis reveals spikes in CPU utilization that last 5 minutes on an Amazon EC2 Linux instance. A SysOps administrator is tasked with finding the process ID (PID) of the service or process that is consuming more CPU.
How can the administrator accomplish this with the LEAST amount of effort?

  • A. Configure an AWS Lambda function in Python 3.7 to run every minute to capture the PID and send a notification.
  • B. Configure the procstat plugin to collect and send CPU metrics for the running processes.
  • C. Log in to the EC2 Linux instance using a .pem key each night and then run the top command.
  • D. Use the default Amazon CloudWatch CPU utilization metric to capture the PID in the CloudWatch dashboard.

Selected Answer: B
The procstat plugin is part of the Amazon CloudWatch agent, which can be installed on the EC2 Linux instance. This plugin is specifically designed to monitor individual processes and collect CPU and memory metrics for those processes. By configuring the procstat plugin, you can easily monitor CPU utilization for running processes on the instance.
