that has hardly anything to do with collectd: collection.cgi is based on
a script I wrote to display graphs some time ago. Back then I collected
the data using a bunch of shell- and perl-scripts.. IIrc the mail-script
worked with postfix and used the perl-module `File::ReadBackwards' to
read the logfile..

The `disk' RRD files have data sources (DS) named `rtime' and `wtime'.
These are some mysterious `time' values from `/proc/diskstats'. I'm not
entirely sure what exactly these values mean and couldn't find that out
either.. If you do, please let me know :)

If you substitute the `/day' at the end of the URL for the daily graph
with `/week', `/month' or `/year' you get the according graphs..

The `museum.cgi' is not up-to-date right now since I'm focussing on
collection.cgi which will be much improved in the next version..

Yeah, I forgot that.. It's fixed in the svn..
