NAME
       dsc - DNS Statistics Collector

SYNOPSIS
       dsc [ -dfpmiTv ]	dsc.conf

DESCRIPTION
       DNS  Statistics	Collector  (dsc) is a tool used	for collecting and ex-
       ploring statistics from busy DNS	servers.  It can be used in a distrib-
       uted  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.

OPTIONS
       -d     Debug mode.  Exits after first write.

       -f     Foreground mode.	Don't become a daemon.

       -p     Don't put	interface in promiscuous mode.

       -m     Enable monitor mode on interfaces.

       -i     Enable immediate mode on interfaces.

       -T     Disable the usage	of threads.

       -D     Don't exit after first write when	in debug mode.

       -v     Print version and	exit.

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 re-
       sults 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.
