Setup Bind 9 DNS Logging and Statistics

Logging

To setup logging in Bind 9 you will need to complete the following:

First configure logging in your named.conf.options file

sudo nano /etc/bind/named.conf.options

Add this at the bottom of the file:

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

Now create a directory for the logs.  Unless you edit  your /etc/apparmor.d/usr.sbin.named, you will have to use the default directory of /var/log/named/:

sudo mkdir /var/log/named

sudo chown bind:bind /var/log/named

sudo touch /var/log/named/query.log

sudo chown bind:bind /var/log/named/query.log

Now restart Bind

sudo service bind9 restart

Statistics

To setup statistics in Bind 9 you will need to complete the following:

First configure statistics in your named.conf.options

sudo nano /etc/bind/named.conf.options

Add this line:

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

Now run the following command:

sudo rndc stats

Now you need to restart Bind

sudo service bind9 restart
