The way we usully do exactly this on our networks is to use something called “Smokeping”. Go here for more info: http://oss.oetiker.ch/smokeping

Out of the box it would do what you want i.e. monitoring an address, if that suffers XYZ packet loss to alert you via mail/script.

Measuring packet loss of DNS lookups to Google’s 8.8.8.8 server?

You can create two dummy firewall rules that don’t do anything other than count packets.
1 for counting outbound UDP port 53 packets to 8.8.8.8 where action = passthrough
1 for counting inbound udp port 53 packets from 8.8.8.8 where action = passthrough

Mikrotiks already count packets.

Then have a script that runs every x amount of hours. Compare how many DNS requests were sent, how many replies received. There should be one reply per request.
requests - replies = packets lost, send email to yourself. Clear counters for both those rules.
