}
the RRD files are generated by collectd into the directory
/var/lib/collectd/rrd/kessel0001.fritz.box/biosmart, and i created a symlink
pointing so graphit finds them under
/var/lib/graphite/rrd/kessel0001_fritz_box/biosmart .
Graphite find the files and displays all the available rrd files in the tree
view to the left of the screen. I can select a couple of values and create a
plot. however, the graphs are not rendered. when accessing the URL to the
rendered graph directly, i get a python traceback:

there is plenty (24h+ worth) of data in the rrd files. however i let collectd
create the rrd files with this collectd config:
RRATimespan 3600
RRATimespan 86400
RRATimespan 604800
RRATimespan 2678400
RRATimespan 31622400
RRATimespan 315576000
the last line will hold data of 10 years, which will only get the first data
point after (i think) 3 days. Will it take that long till the graphs are
viewable? can i shorten that time? can i pre-seed the rrd files somehow? or is
this traceback caused by a different error? what would be a simple fix?
