Count daily bandwidth usage for multiple sites on a Server.
SlimLogger enables a server owner to determine which sites are using the bandwidth to and from the computer. Unlike most traffic monitoring programs which operate purely based on IP number, SlimLogger defines a site based on a combination of settings, which can include one or more web domain names, ftp traffic, plus tcp or udp traffic on given ports. SlimLogger's output is very simple: a single report for each site, showing bytes transferred to and from the server for that site. SlimLogger stores the counts in an XML database, which, if you have appropriate tools, you can query to create further reports.
