Is it possible to trace which file or process or database query is effecting the load on a VPS?
I am using Centos with 512 MB Guarantee Memory and 1 GB burst Memory, I am running 3 wordpress sites from it, where all are having daily traffic of 30-100 visitors each,
After every 2-3 days I need to restart my VPS because the resources are taking high usage of memory,
I tried running
top command and it shows Apache as high,
But is it possible to check which website is taking load?
Here is my 'top -c' command output results
