Hi Endore,

The official answer will probably be: "No, PowerDNS doesn't supply a  
script for FreeBSD that automatically invokes mrtg on the  
statistics.". But I'm not in a position state such things officially.

Let me try to help you though.

First of all, the (debian) rcscript supplied by pdns is not installed  
on FreeBSD, since its not linux.

You can have a look at that script yourself by downloading the sources  
of PowerDNS. A quick glance shows me that you can edit your mrtg  
config, and replace the occurances of
	/etc/init.d/pdns mrtg
with this command:
	/usr/bin/pdns_control show

You can test this by executing this command:

	# pdns_control show udp-queries udp-answers

It should output 2 numbers, each on 1 line.

With this information you should be able to make that MRTG  
configurationw work on FreeBSD.

NB: The documentation on pdns_control is not up-to-date on this "show"  
command. But it just takes 1 or more arguments of the counters to spit  
out.

Good luck,
Kai
