I've done some work on just such a thing. It works locally, but needs
quite some finishing off to make it presentable: probably two or three
full days, without interrupting demands from the day job. This isn't
top of my list just now.
What I've tried to produce is a lightweight display tool which can
display either the traditional MRTG-generated displays or closely
equivalent on-demand displays from RRD data collected by MRTG. As
far as possible, existing MRTG configuration data is used. This
makes it useful in facilitating migration from LOG to RRD format,
and allows "normal service" to continue while one is learning how
best to make use of more sophisticated display front-ends.
Some specific configuration is needed: the web server must be set
up to provide a CGI interface to the application, and the location
of the directory where the MRTG configurations live must be
specified. Naturally, write access to the directory (-ies) where
on-demand images will be created is needed.
If that sounds useful, let me know; I may become minded to try to
give it a higher place on that list.
