NAME
     dsc - DNS Statistics Collector

SYNOPSIS
     dsc [ -dfpmiTv ] dsc.conf

DESCRIPTION
     DNS  Statistics Collector (dsc) is a tool used for collecting and exploring
     statistics from busy DNS servers.	It can be set up to run on or near name-
     servers to generate aggregated data that can then be transported to central
     systems for processing, displaying and archiving.

     Together with dsc-datatool the aggregated data can be furthur enriched  and
     converted	for  import into for example InfluxDB which can then be accessed
     by Grafana for visualzation, see this wiki on how to set up that:

	    https://github.com/DNS-OARC/dsc-datatool/wiki/Setting-up-a-test-
	    Grafana

     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 struc-
     ture and output filenames.

KNOWN ISSUES
     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.
