I am new to server administration and have just setup a new quad core instance which hosts around 15 websites.
Over the past couple of days my server load has been averaging at around 15.00. I believe it is because of one (or maybe more) websites are getting spammed by spambots.
Typing 'top' at the command line shows many processes from user 'www-data' which indicates lots of web traffic. Is there an easy way identify which one of my sites is taking a hammering?
Reading the apache error logs is a very difficult tasks as most of the websites receive daily traffic of 10,000 + unique users.
Any help would be appreciated!
