dsc − DNS Statistics Collector
dsc [ −dfpmiTv ] dsc.conf
DNS Statistics Collector (dsc) is a tool used for collecting and exploring statistics from busy DNS servers. It can be used in a distributed architecture to run collectors on or near nameservers sending their data to one or more central presenters for display and archiving.
dsc will chroot to a directory on startup and output statistics into files in various formats.
See dsc.conf(5) on how to configure dsc, what formats exists, their structure and output filenames.

This program and/or components uses select(2) to wait for packets and there may be an internal delay within that call during startup that results in missed packets. As a workaround, set pcap_thread_timeout ( see dsc.conf(5) ) to a relevant millisecond timeout with regards to the queries per second (QPS) received. For example if your receiving 10 QPS then you have 20 packets per second (PPS) and if spread out equally over a second you have a packet per 50 ms which you can use as timeout value. Since version 2.4.0 the default is 100 ms.
