Ok Karl, here you go… Once you have installed RTG on your server from FreeBSD ports and configured it, you can add this script to your /usr/local/etc/rc.d/ folder.  Make sure it runs AFTER your mysql server starts or it will be useless!

#!/bin/sh

case “$1” in
‘start’)
rm /tmp/rtgpoll.pid
/usr/local/bin/rtgpoll -c /usr/local/etc/rtg/rtg.conf -t /usr/local/etc/rtg/targets.cfg &
;;
‘stop’)
;;
*)
echo “Please specify ‘start’ or ‘stop'”
;;
esac
