When I receive DDOS attacks, my processor usage goes to 100%, meaning Cloudflare is not mitigating. What can I do?

are the requests going through cloudflare?

do you have dynamic parts of your website that require processing on your device?

If you are under a DDoS attack then you can take a look at these threads for first steps and help with mitigation:

Yes, requests go through cloudflare. I didn't understand the other question.

Machine processor usage without attack: 15%, then with attack 75%, mysql using around 80% according to what htop says, and then when I disabled mysql the machine's cpu usage with the attack was 25% (+ 10%) then I activated mariadb again and it was at 70%.

#

any suggestions for this?

How do I disable any request to my website if Cloudflare detects ddos?
