That reminds me of one of the features I want to add to drraw.  I want
to add an embeddable mode, where you can call drraw from within
another CGI and have it output the HTML for a particular
graph/template/dashboard.  In particular the front page of
http://stats.net.cmu.edu basically contains the content of one of my
drraw dashboards, but everytime I update the dashboard I have to
cut-n-paste the HTML into that page.  I'd rather have a "include
dashboard #XXXXX here" feature.

I haven't seen that, the only trending stuff I've seen is the Holt
Winters code.  Any idea where you saw it?

I swear I figured out how to do this at one point, maybe I just did a
dump/edit/restore by hand.  These days I have the HWPREDICT stuff
enabled in my top level cricket defaults, so they exist in all the
data.

If I understand correctly the currect cricket code uses descriptive
names in the rrd datasources.  Of course that requires re-creating the
rrds...

However at LISA I got the impression that no one is using cricket any
more...  Most of the folks at the rrdtool bof were using Cacti.  I'm
thinking I may look into Cacti again, it sounds like its gotten a lot
better then the last time I looked at it.
