Hi there @shiraski,

It looks like there are a lot of PHP-FPM processes that are causing the high CPU usage on your server.

What I could suggest is using this script here which will summarize your Nginx access logs. That way you will be able to tell if the traffic that you are getting is legitimate or not.

If the traffic is legitimate, I would recommend doing some optimization for your Magento server so that it does not need so much CPU resources. For example as a start you could do:

• Enable caching
• Enable flat catalogue
• Add a CDN in front of your web server
• Enable PHP OpCache

Let me know how it goes.
Regards,
Bobby
