AWS CloudWatch - 100% CPU Utilization

1
votes

I have an AWS M4.Large EC2 instance running a Magento e-commerce site that is experiencing consistent max CPU usage spikes at a regular interval: 10 minutes at 100% CPU, followed by 20 minutes at 40-50% CPU. I've included a screenshot below. I am trying to identify the cause of these routine spikes, but am not sure how to target the cause(s). I would assume an automated task is at play here, due to the regularity of these spikes. Any advice and suggestions would be extremely appreciated!

I am hoping to keep our instance type as an M4.Large, but if it requires an increase then I will bump it up. Unfortunately, I do not think that AWS Auto Scaling will be a viable option this web application.

Thank you! Suggestions are very much appreciated!

EDIT: While looking at the Network monitors, it seems that high traffic correlates exactly to the CPU usage.

Have you looked at something like TOP and actively monitored the processes? – Nicholas Martinez

Have you enabled the access logs if yes then you can easily figure it out whether the requests are coming from your automation module or not.

How to differentiate original request from automation requests You can add some extra query parameter to the url, Now you can start tracing all the requests generated by your automation module during that time.
