Enable advanced logging for DDNS updates in nameserver (bind9).

Step 1

Stop nameserver
systemctl stop bind9

Step 2

Edit configuration files manually:

cat /etc/bind/named.conf.samba4 | sed s%dlopen /usr/lib/x86_64-linux-gnu/samba/bind9/ -d 0%dlopen /usr/lib/x86_64-linux-gnu/samba/bind9/ -d 3%g > /etc/bind/named.conf.samba4.neu

And move them into place:
mv /etc/bind/named.conf.samba4.neu /etc/bind/named.conf.samba4

Step 3

Start bind nameserver in foreground:

named -c /etc/bind/named.conf.samba4 -f -g 2>&1 | tee /tmp/named.log

Step 4

Let it run as long as you need it and stop the process by pressing Ctrl-C.

Step 5

Analyse the resulting file /tmp/named.log for information you are looking for.

Revert the manual changes and restart the nameserver to perform as before:

ucr commit /etc/bind/named.conf.samba4
systemctl restart bind9 nscd
