IMHO, there is nothing nsd-specific. You just use a generic monitoring
framework. I use Icinga <http://www.icinga.org/> but there are many
others.

Like most tools, Icinga accepts the Nagios API so you can use the
Monitoring plugins (former Nagios plugins)
<https://www.monitoring-plugins.org/> I use an unmodified check_dns,
configured that way in Icinga:

define service{
        use                             generic-service        
        host_name                       mononoke
        service_description             DNS4
        check_command                   check_dig!-4 -l eu.org -T SOA -A +dnssec
        }

define service{
        use                             generic-service        
        host_name                       mononoke
        service_description             DNS6
        check_command                   check_dig!-6 -l eu.org -T SOA -A +dnssec
        }
