Bind9 Plugin

bind9 server config

Bind server needs to be configured to log queries. You can do so by adding to /etc/bind/named.conf.options

logging {
        channel b_query {
                file "/var/log/bind9/query.log" versions 2 size 1m;
                print-time yes;
                severity info;
        };
        category queries { b_query; };
};

Now, make the directory and give it the right permission:

# mkdir /var/log/bind9
# chown bind:bind /var/log/bind9
# /etc/init.d/bind9 restart

munin node config

Set up the file correctly:

# ln -s /usr/share/munin/plugins/bind9 /etc/munin/plugins/bind9
# touch /var/lib/munin/plugin-state/bind9.state
# chown munin:munin /var/lib/munin/plugin-state/bind9.state

In /etc/munin/plugin-conf.d/munin-node make sure you have declared bind9 plugin:

[bind9]
user root

and restart munin-node

# /etc/init.d/munin-node restart

Bind9_rndc Plugin

bind9 server config

Your default bind install should already write to /var/cache/bind/named.stats when running the command:

# rndc stats

If not, make sure you have the following directive within options group in /etc/bind/named.conf.options:

        statistics-file "/var/cache/bind/named.stats";

Now, restart bind:

# /etc/init.d/bind9 restart

munin node config

First, link the plugin to Munin plugin folder:

# ln -s /usr/share/munin/plugins/bind9_rndc /etc/munin/plugins/bind9_rndc

In /etc/munin/plugin-conf.d/munin-node make sure you have declared bind9_rndc plugin:

[bind9_rndc]
user root
env.querystats /var/cache/bind/named.stats

and restart munin-node

# /etc/init.d/munin-node restart
