First, Thank You for your swift answer!
So, since you do not mention a guide, i assume, there is none?
What i did already:
I added a file smartd.conf to /usr/lib/collectd/collectd.conf.d/, with the following content:
LoadPlugin smart
<Plugin smart>
UseSerial true
</Plugin>When i restart collectd via /etc/init.d/collectd restart, it fails, and my logfile is filled with:

Apr 2 18:28:28 medien systemd[1]: collectd.service: Failed with result 'exit-code'.I found a lot of already filled rrd files (like entropy, users, irq etc.) in the "datadir", /var/lib/collectd/rrd/$hostname.$myFQDN , how do i get them to be displayed , maybe under the Diagnostics-->System Information-->Performance Statistics panel, where all the other graphics reside?
I cannot find where generation of these data is initiated, at least not in /etc/collectd/collectd.d/. What config files are responsible for this, and where do they live?
How do i get the disk statistics graphics (the BTW: in my first post) to reappear?
