Yes smartcoin is included and has been tested. Also you can now view the stats of smartcoin via the munin web interface. When you've booted you need to symlink the plugin and wait around 10 mins for munin to update.
ln -s /usr/share/munin/plugins/smartcoin /etc/munin/plugins/
then you can view this information on the local machine by viewinghttp://127.0.0.1/munin
or from another device by viewing http://<your_ip>/munin
