Hello,

I could suggest following the steps here on how to find the processes that are consuming the most server resources:

Regarding your server logs, you can find them at the /var/log directory and you can use the cat or tail commands to check a specific log. For example, if you had an Nginx server and you wanted to check the last 100 lines of the Nginx log, you could use the following command:

tail -100 /var/log/nginx/access.log

Also if you have an Apache or Nginx server, you could use the following script to analyze the logs and see if there are any suspicious amount of requests coming from a specific set of IP addresses:

Let me know how it goes. Best, Bobby
