Question Apache CPU high!

[CoyoteKG]

Hello,

I migrated Magento 1.9 site from one server with plesk 12.5 to new server Plesk Onyx.
Before I did not noticed that CPU is so high. I checked via "htop" and there looks normally.

Now I look at Onyx panel and Health monitoring warning that Apache CPU is very high. At one moment was almost 60%




This is from htop




Can you tell me if is it real alarm? And how to diagnose what happening

OK, I see in access logs that for few minutes site is crawled by 700 different IP-s

I disallow it robot.txt, and added some list in .htaccess, but nothing better...

Hi CoyoteKG,

I disallow it robot.txt, and added some list in .htaccess,

You should consider to use for example Clouflare, or any other related CDN - service.
