though there are some plugins with domain specific data I don't think
this will help you much with the problem you describe. I would search
http://exchange.munin-monitoring.org/ for contributed plugins. Munin
will never be able to tell you a hostname/IP on the webpage.
To get to the host in question I would use some apache logfile analyser
like analog or webalizer to condense the logfile information. Tracking
down DoS hosts is done by browsing the logs, so if the DoS is a big one,
you might only have to take a quick look at logs to see the matter.
