BIND9 aka named

1. Configure Cache file

Create stats file with appropriate permissions:

touch /var/cache/bind/stats
chown bind:bind /var/cache/bind/stats

2. Bind/named configuration:

options {
    ...
    statistics-file "/var/cache/bind/stats";
    zone-statistics yes;
    ...
};

3. Restart your bind9/named after changing the configuration.

sudo systemctl restart bind

4. Verify that everything works

You can verify by executing rndc stats && cat /var/cache/bind/stats.

6. Install Prerequisites

The script for this also requires the Perl module File::ReadBackwards.

pkg install p5-File-ReadBackwards

yum install perl-File-ReadBackwards

sudo apt-get install libfile-readbackwards-perl

If it is not available, it can be installed by cpan -i File::ReadBackwards.

7. The agent script or the extend script can also need configuration.

The config file's path defaults to the same path as the script, but with .config appended. So if the script is located at /etc/snmp/bind, the config file is /etc/snmp/bind.config. Alternatively you can also specify a config via -c $file.

Anything starting with a # is comment. The format for variables are $variable=$value. Empty lines are ignored. Spaces and tabs at either the start or end of a line are ignored.

Content of an example /etc/snmp/bind.config . Please edit with your own settings.

rndc = The path to rndc. Default: /usr/bin/env rndc
call_rndc = A 0/1 boolean on whether or not to call rndc stats.
    Suggest to set to 0 if using netdata. Default: 1
stats_file = The path to the named stats file. Default: /var/cache/bind/stats
agent = A 0/1 boolean for if this is being used as a LibreNMS
    agent or not. Default: 0
zero_stats = A 0/1 boolean for if the stats file should be zeroed
    first. Default: 0 (1 if guessed)

If you want to guess at the configuration, call the script with -g The script then prints its own estimate of the configuration.
