Make sure BIND was built with libxml2 support. You can check with the following command: named -V | grep libxml2.

Configure BIND to open a statistics channel. It's recommended to run the bind_exporter next to BIND, so it's only necessary to open a port locally.

statistics-channels {
  inet 127.0.0.1 port 8053 allow { 127.0.0.1; };
};
