If you don't have an IPv6 address bound to this jail, disable IPv6 and the IPv4 port binding:
cd /usr/local/etc/lighttpd sed -i .bak -e 's/server.use-ipv6 = "enable"/server.use-ipv6 = "disable"/' lighttpd.conf sed -i .bak -e 's/^\$SERVER\["socket"\]/#\$SERVER\["socket"\]/' lighttpd.conf
start lighttpd
echo 'lighttpd_enable=YES' >> /etc/rc.conf service lighttpd start

Install the munin master (data collector):
pkg install -y munin-master
configure munin master
