DNS Statistics Collector (DSC) is a tool used for collecting and exploring statistics from busy DNS servers. It uses a distributed architecture with collectors running on or near nameservers sending their data to one or more central presenters for display and archiving. Collectors use pcap to sniff network traffic. They transmit aggregated data to the presenter as XML data. dsc requires a couple of libraries beside a normal C compiling environment with autoconf, automake, libtool and pkgconfig.
