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. You may possibly need to configure the agent/extend script as well.

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 will be /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 and it will print out what it thinks it should be.
