[rrd-users] Making Tables of RRD Data?

I have an RRD which is collecting live statistics on about 20 different
boxes... What I want to do is have RRDTool dump data from certain DS's (i.e.
max value, min value, average, etc) for the past 24 hours as text so I can
build tables in HTML.

How do I tell RRDTool tol dump- for example the MAX value from a DS called
CPUIdle-mgm-fr1m from the past 24 hours? Is there a way I can tell RRDTool
to specifically dump the value from that DS? Can RRDCGI do this? If so I
haven't managed to figure out how yet!

So far the only way I have managed to do it is to write a perl script that
does a fetch on the past 24 hours of all data and then hand pick what I
want, but this is not really practical and I am sure RRDTool can do the job
