DNS Statistics Collector
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 nameservers 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:

Dependencies
dsc requires a couple of libraries beside a normal C compiling
environment with autoconf, automake, libtool and pkgconfig.
dsc has a non-optional dependency on the PCAP library and optional
dependency on the MaxMindDB library (for the asn and country indexer).
To install the dependencies under Debian/Ubuntu:
apt-get install -y libpcap-dev
To install the dependencies under CentOS (with EPEL/PowerTools enabled):
yum install -y libpcap-devel
To install the dependencies under FreeBSD 10+ using pkg:
pkg install -y libpcap
NOTE: It is recommended to install the PCAP library from source/ports on OpenBSD since the bundled version is an older and modified version.
DNSTAP support
To enable DNSTAP support, first install the necessary dependencies and
then run configure with --enable-dnstap.
- Debian/Ubuntu:
apt-get install -y libdnswire-dev libuv1-dev - CentOS:
yum install -y dnswire-devel libuv-devel - FreeBSD:
pkg install -y libuv - OpenBSD:
pkg_add libuv
dnswire packages for Debian, Ubuntu and CentOS exists at
https://dev.dns-oarc.net/packages/,
for other distributions please see
https://github.com/DNS-OARC/dnswire.
Building from source tarball
The source tarball from DNS-OARC
comes prepared with configure:
tar zxvf dsc-version.tar.gz
cd dsc-version
./configure [options]
make
make install
NOTE: If building fails on FreeBSD/OpenBSD, try adding these configure
options: --with-extra-cflags="-I /usr/local/include" --with-extra-ldflags="-L/usr/local/lib".
Building from Git repository
If you are building dsc from it's Git repository you will first need
to initiate the Git submodules that exists and later create autoconf/automake
files, this will require a build environment with autoconf, automake, libtool
and pkgconfig to be installed.
git clone https://github.com/DNS-OARC/dsc.git
cd dsc
git submodule update --init
./autogen.sh
./configure [options]
make
make install
NOTE: If building fails on FreeBSD/OpenBSD, try adding these configure
options: --with-extra-cflags="-I /usr/local/include" --with-extra-ldflags="-L/usr/local/lib".
Puppet
John Bond at ICANN DNS Engineering team has developed a puppet module for DSC, the module and code can be found here:
