myVesta

I'm using my vesta for a long time but suddenly on my website, I can see PHP fpm taking all my CPU causing my site to slow down. Amazon ec2 free tier. I tried on Linode too.

Go to "SERVER" in upper menu
Then go to "show: CPU / MEM / NET / DISK"
Then go to "WEB"

You will see who is making http flood, and with what URL request, and you can block their IP in "Firewall" section.
