This sounds like a variable number of measurements (one per folder) with 
a fixed number of parameters per measurement (one (size) or two 
(size,max)). In that case you should use  the '--extra-test' option (see 
http://www.hswn.dk/hobbit/help/manpages/man8/hobbitd_rrd.8.html). You 
probably also need a script to build the header of each graph. If you 
like, I can send you sample scripts.

Within the body of the status message, you'll include the measured 
values in NCV format, which might be embedded in HTML comment. Note that 
you might need to change other lines in the status message in order to 
avoid them to be interpreted as NCV. One way of doing so is to replace 
each ":" by ":" and each "=" by "=". The script named in 
"--extra-test" writes those values to RRDs. O, include a line in the 
status message, before the measurements, stating the number of 
measurements, that is include a line with "<!-- linecount=N -->" with a 
suitable value for N.

Kind regards,
