Too many httpd request in centos
From past 2 days I have noticed that my server has become very slow and today I see that the CPU usage in 100%
On further investigating found that there are lot of https request, mostly they might be bots.
I am centos and I have VestaCP installed and few sites running which consume max of 40GB of total bandwidth per month.
As you can see there are more httpd request making my all website not reachable. Can any one help me on this
